Supernova – fission explosion? A precursor neutron star?

 

Cassiopeia A        NASA / JPL/ Caltech

Might one consider any SN1987 precursor star as a predominantly fusion star, as a source of energy; wherein one has gravitational collapse to a critical mass density, and then fission process commencing and predominating? Higher mass element nucleosynthesis would require free neutrons; thus wouldn’t nuclei fission be required?

If there is no detectable precursor star, might this be consistent with just a solo neutron star acquiring additional mass, or internal dynamics leading to run away explosive fission process i.e. supernova? Perhaps an internal/external circulating plasma in magnetic field of such neutron star, and redistribution of energy (magnetic reconnect – entanglement ?), leading to instabilities, such as localized change in neutron density?

What might be consistent with a supernova precursor being a neutron star? Since the supernova database continues to get bigger (including association with most long duration GRB), might one eventually match it to x-ray binary database (Chandra) in order to notice overlap of any SN with planar patch for x-ray binary? Then, if practical, see if a binary star is still there. If present, then might SN have originated from secondary compact object of x-ray binary?

Could one then consider the odds of any such alleged association, by comparing respective x-ray binary and gamma ray burst databases for association; such latter comparison, currently null?

Might another approach to any supernova remnant SNR, be to look for any motion of luminous star very near to SN1987 co-ordinates; within 1/2 arcsecond? That is, SN are anisotropic, as revealed by their effective absence in globular clusters. Therefore would any stellar motion  be evidence of a precursor binary? Also utilize infrared spectroscopy, looking for any remnant object, as elaborated on, below?

Shock waves expanding at 10s of thausands km/sec; whereas stellar natal kick might be at just ~1000 km/sec.? For the latter velocity of any possible surviving star of 1987 SN possible binary, for over 30 years, at a distance of ~165,0oo lyrs, what would be the angular displacement; discernable?

As critical mass density (sufficient for sustained chain reaction)  is reached, might one also have an energy density associated with eventual red dwarf formation? Perhaps the latter not just a remnant, but consistent with a fission process, contributing additionally (or solely) to what we detect as a supernova explosion?

Stars contain an abundance of iron (as per spectroscopy), not unlike earth and stellar nebula. If cosmic rays are predominantly iron nuclei, them might this also be consistent with a supernova fission process, including (mainly?) iron? But where is iron in a SN explosion? One has evidence of nickel and cobalt; both next (in atomic number and weight) to iron in Periodic Table. Are iron nuclei being utilized and consumed as a fissionable fuel in such SN explosion and element synthesis?

Might such considered fission process (perhaps iron doped with .1% uranium?), trigger off a supernova explosion, rather than just being an accompanying process? Might additional energy released be mainly massive neutrinos? In terms of energetics, is most of energy released in supernova explosion from neutrinos? Does fission process generate more neutrinos, as well as heat, than fusion?

Is the energy scale for SN limited to just 2 fermion generations (i.e muons) or might one have higher energy levels associated with fermion mass spectrum? What energy (mass density) scale is associated with (if) neutrino trapping; approximately same as for neutron (nucleon) degeneracy? But less than short duration GRB energy scale?

If higher energy scale, as for fermion mass spectrum, then one would seem to have left over higher generation massive neutrinos. Assuming no decay nor annihilation, and comparatively limited nucleon absorption, might our galaxy (including dark matter halo?), Large Magellanic Cloud, and solar system’s neutrino belt, contain a smaller fractional number of such more massive neutrinos, in addition to electron neutrinos?

Might a supernova explosion description be more than just release of gravitational potential energy, and more than just a bounce off an energy (i.e. mass density) nucleon (?) surface (simulations not consistent with such bounce?); and more than just a fusion process, since fuel has been markedly reduced? Instead might such explosion represent a qualitative and quantitative shift to a predominant fission process, with also perhaps a remnant, suggestive of such switch?

What is the most likely outcome of a supernova – no remnant? Might any database of supernova remnants (SNR) contain a compact object; a significant portion of original massive star? Would a pulsar be part of any such SNR database? Might likelihood of compact object be mass (10-15 solar mass?) dependent? What percentage of neutron stars are pulsars? If there were a supernova remnant, might it be of a lesser mass, such as red dwarf mass?

Or if a neutron star were a SN1987 remnant, then wouldn’t there be central x-ray detection, from strong magnetic field, near infall to magnetic pole? Might one have both a SN precursor neutron star, and also a somewhat lesser mass NS? But would there be sufficient fuel for SN in such scenario?

Could a supernova explosion sometimes leave behind a red dwarf remnant (i.e. SNR) fission star (such as .04 of 4 solar mass precursor), usually detectable only in infrared? Would infrared spectroscopy enable detection of such an object?

For example, might infrared spectroscopy distinguish between heat of expanding gas shell and an interior remnant source? Even if the site of SN1987 is obscured by gas clouds, inter-stellar debris etc., still might infrared spectroscopy reveal an object at SN1987 co-ordinates? Whereas gas clouds, and other diffuse infrared sources, might just reveal a slight non-specific pattern.

Thus would any such infrared spectroscopy detection (and thus revealed object?) seem consistent with the significance of a fission process in initiation of explosiveness of supernova phenomena?

Martian stromatolites?

Filed under: Letters from Ionia — Tags: , , — zankaon @ 4:11 pm

Might there be detectable stromatolites on Mars; left over from long ago nascent life? Perhaps would an all planet survey with synthetic aperture radar (SAR), with resolution of ~ 10 cm, suffice?

Neutrino magnetophere retention; charged particle enhancement of magnetic field?

Filed under: Letters from Ionia — Tags: , , , , — zankaon @ 2:23 pm

What is alleged incidence of solar neutrino per square centimeter penetrating us? Or is such a question just lore?

Wouldn’t massive neutrino with a magnetic moment be deflected by earth’s magnetosphere; then perhaps ‘sliding off’, and escaping to outer solar system? Or would such captured neutrinos flow into one of earth’s magnetic poles, and end up accumulating in center of earth; or re-cyclng in magnetosphere? If so, how many neutrino would accrue, for our magnetosphere, over age of earth?

For charged particles of solar wind – likewise? Also over 4.6 billion years, has this contributed to strenthening of magnetic field? Any other effect of accumulation of charge over such long period of time?

Might the stronger magnetic field of Mercury, despite it’s smaller mass, have been enhanced by capture and retention of charged particles from more intense solar wind, for over billions of years? Hence consistent with such effect (albeit comparatively lesser extent?) for earth?

If all stars, including compact objects, have a magnetic field, then a contribution of charged quanta to enhancement of such field? Thus also for black hole, an accumulation, and influx of charged quanta recycling in internal and external magnetosphere; giving rise to a charged compact object?

JunoCam polar jovian images – suggestive of a surface in part? Also a possible underlying Saturnian surface?

Filed under: Letters from Ionia — Tags: , , , , , , — zankaon @ 12:34 pm

Might NASA JunoCam images of Jupiter’s polar region, from 23,000 miles, suggest a surface; or just an underlying surface? Rather than just atmospherics, might one be seeing in part a liquid or rock/ice surface (percentage ice and/or rock)? Or perhaps more ice crystalization in atmosphere? Would synthetic aperture radar (SAR) distinguish a predominantly rock surface? Do such polar images look more like icy Jovian moon surfaces, or like Pluto; or in part more like a rocky/ice surface; or just lower velocity winds’ effect?

Would rapid rotation (~10 hrs) of Jupiter affect polar region atmospheric circulation etc., giving rise to a different presentation?

However wouldn’t the lower density of Jupiter, compared to density of terrestrials, seem consistent with a gaseous predominance, and not even just a predominant ice/liquid interior?

Might one even entertain the possibility of just a gaseous jovian ‘moon’? Is the Great Red Spot (GRT) more than just a cyclonic-like disturbance? Is it’s density extremely different (5-10x ?) than ambient clouds; hence a much greater (terrestrial scale) mass? Sufficient mass to designate it a gaseous object in fixed co-rotation with visible ambient clouds? More specifically, consider it’s depth equal to it’s diameter, giving ellipsoid volume. Could ellipsoid shape, vs conical or cylindrical, be ascertained by oblique SAR radar imaging? That is, might an underlying curvature vs flat surface be consisent with such ellipsoid shape?

Then for ascertained density, obtain mass. Then compare such mass to a Titan’s estimated all ice density mass, to see if GRT has comparable mass.

Might past ‘comet’, or jovian moon icebergs, collision suggest hitting a surface, rather than atmospheric/liquid explosions?

Just as there are external rings/bands, might there also possibly be a somewhat interior orbiting band(s), or spherical shell, of rock/ice of sufficient density and thickness to constitute a surface, at a certain depth beneath clouds? Hence accounting for ‘comet’ impact pattern?

Perhaps consider a primordial scenario, wherein one has extreme higher angular momentum forming icy clouds, with impurities forming denser conglomerates aggregating (i.e. ice condensation from millimeter grains to decimeter pebbles in 1000 years; the latter constituting protoplanetary disks?) (1), giving sediment-like icy layering accumulating gradually over 4.6 Byrs; resulting in a surface of certain density and structural thickness, in orbit between cloud layers?

Perhaps aeolian effect of high velocity winds contributing to surface formation, as on earth. Might such surface have initially formed much deeper, and then vis a vis exchange of momentum have migrated to outward region? Yet over all planet density unaffected; hence maintaining a non-terrestial profile?

Might one even have other variations for different hot (and for ours) Jupiter’s, such as interior solid ‘moon’ formation, co-rotating with planet, but in the clouds?

Would a Cassini like Saturnian orbit sweeping up obliquely from lower latitude to poles be suitable for detecting via synthetic aperture radar any interior bands, interior ‘moon’, or even planetary wide thick spherical shell? Perhaps redirect Cassini to Jupiter – a 1-2 year voyage?

Might Saturnian circumpolar hexagonal pattern of supposed jet(s) flow be guided (or about?) by an underlying surface , such as ice (all of interior area of hexagon?) at a certain depth below cloud top? Analogy to circumpolar Antarctica current (fluid) and it’s enclosed surface?

Or perhaps an analogy to polygon subsurface formation in permafrost? Perhaps utilize synthetic aperture radar (SAR) of Cassini for such possible surface detection? Or for an ice surface (i.e. object), perhaps infrared spectroscopy would be more suitable. Also polygon formatiion has been observed on Mars; from sub-surface ice.

One could consider rotation of such polygon, but at a rate slower than for any south pole markers in gaseous mileau. That is, such solid ice surface would have a moment of inertia, and hence a slower angular velocity than for gaseous south saturnian pole.

Do such two examples, one of Saturnian icy polygon surface (1/2 continental diameter?), and the other of markedly different gas density (Great Red Spot), represent objects in ‘orbit’ within atmospheric fluid mileau of 2 gas giants?

Since Jupiter/earth radius is ~11/1, then for Jupiter circumference of ~66 times greater, but with rotation period of ~ 10 hrs, what would the top layer cloud velocity be; and would it be in step with observed clouds’ high velocities? Lesser velocity for near poles?

Might strong magnetic fields of Mercury, Earth, and Jupiter all suggest similarities to their interiors? That is, perhaps a surface with a deeper liquid (iron?) inner core, rheologically flowing; in addition to a solid core? Contrast to comparatively lesser magnetic field of Sun, perhaps due to a circulating plasma, rather than liquid? However see above density argument caveat.

Athabaskan language group migrations

Filed under: Letters from Ionia — zankaon @ 6:35 pm

yáʼátʼééh

Athabaskan language groups indicate a relatedness of Arctic and Western Canadian, and Southwest groups, such as Navajo and Apache.
Might also ancient (5-10k yrs ago?) Indian mounds in Minnesota indicate an earlier migrating arctic people; the latter suggested by building style of grave sites? Also the number of generations (related to mound size) would seem too great for just a later Hopewell culture (more southern and eastern) indian mound building style influence.

So before the Sioux and Ojibwa migrations, might an Athabaskan language group (or another arctic group) already have arrived at a seemingly more accessible, suitable, and familiar Midwest environment?

Biomass vs cultural ‘mass’ accumulation – any analogies?

Filed under: Letters from Ionia — Tags: , , , — zankaon @ 6:20 pm

Once life takes hold of a planet, might it almost be impossible to eradicate it? Mars would seem a counter example, due to limited biomass, as indicated by hemitite abundance.

For our planet, with it’s abundance of surface water, and long period of time, biomass has built up. Even extinctions might be irrelevant to such build up. For even extreme event of oceans drying up, still anaerobes in deep sediments would seem survivable in some form.

Analogously, once culture has taken hold of a planet, might it be almost impossible to eradicate; that is, if sufficient cultural ‘mass’ i.e. amount, has accumulated? Might this even be independent of it’s biological originator species? In other words, would culture continue to grow and açcumulate, of it’s own accord? Homo culturus, next in our descent? see SRM at  zankaon

For example, for so-called imachina, might a set or network continue to grow, adapt, and evolve? Might it so evolve, without being aware of it? Or would perception have to evolve; wherein perception requires judgment.

As a practical example, one might consider the perception for a driver of how fast a road curve is breaking, having been impaired by an alcoholic drink. Such judgment (i.e. perception) has been temporally ablated, rendering such biological organism to the status of just a machine, which can see, but not intrepret the situation.

For imachina, might the equivalent be to comment out a sub-routine? However perception i.e. judgment, for imachina, might seem to be modeled as involving adjustments to statistical weighing of internodes. But would this have to be of a general and widespread nature, and for a very complex imachina, or network? Is server software already rendering some judgment (rudimentary perception of a situation?) in regards to incomplete applets, yet functional because of a generic substitution?

Might it seem that culture could continue to evolve and accumulate, even without being aware of it, or of a sense of overall selfness?

How old are cometary orbits? Ejected gas giant etiology?

Filed under: Letters from Ionia — zankaon @ 4:12 pm

Since mass loss would seem slight, might a comet’s orbit have originated billion of years ago? Perhaps destabilized from early Oort cloud formation, by an ejected gas giant? So might a collisional effect for Uranus, long period comet orbit formation, and any gas giant ejection from our system, have a relationship? Would such gas giant planet be detectable in infrared, and distinguishable from a sister star red dwarf?

Internal luminosity source for Jovian cloud bands?

Filed under: Letters from Ionia — Tags: , , — zankaon @ 11:53 am

If no external lighting source for apparent brightness of Jovian cloud bands, might such lighting be from emission radiation of ionized plasma at a somewhat deeper layer? Might such emission radiation have some association with ionized gas (plasma) moving along so described magnetic field lines at a somewhat deeper layer? Is there any relationship of luminosity intensity to density of so-called magnetic field lines?

Might any variation of band luminosity be due to cloud band density, and perhaps composition, rather than variation in luminosity source?
In an informal sense, might one entertain an analogy of a luminous corona associated with mass injection and magnetic re-connect i.e. stressed magnetic field? And adapt such processes to deeper jovian layered plasma?

Might also there be no ice crystals in upper cloud layers; since if there were, then any alleged backlighting would seem to result in refraction observable effects.

Calculations and gravitational potential tapering – a problem? Motion for our Sun, as part of a binary system? Parallax resolution?

Might gravitational potential, instead of inversely dropping off linearly, perhaps have a different (exponential like?) tapering? Differently, does the electric field, and also radioactivity, have a sudden drop off? Thus is there perhaps precedence for differences in field strength, and decreases in other phenomenon?

Might such conjecture be consistent with the continued apparent gravitational binding of Proxima centauri in it’s triple star system, even though seeming, through calculations, being too far from other 2 stars? Likewise is gravitational potential seemingly too weak, via calculations, to keep our moon in orbit? Hence might our gravitational potential have a different gradual tapering, not reflected in our calculations or modeling?

Also might any sister red dwarf star actually still be in orbit with our sun, if still far out in weak tapering gravitational potential; not unlike Proxima centauri? If so, then a center of mass for such binary stellar system would be much closer to our sun. Hence might there be an additional detectable motion for our sun, if part of such binary system? Might parallax of a masked sun, giving apparent shifting position of background stars, actually be a composite of earth’s and sun’s respective orbit/motion?

For example, one could compare parallax results for vernal and autumnal equinoxes, which should be periodic. If not, then consistent with such additional parallax being due to a binary stellar companion.

Might one re-measure and reconsider Doppler spectroscopy radial velocity line of sight technique to detect any inapparent periodic frequency shifting  (of absorption lines) due to sun’s position at line of sight opposite sides of any motion? So rather than attributing such radial motion solely to our gas giant (~ 1/1000 of solar mass), might one have a larger component contribution from such considered center of mass for a binary stellar system?

For hot Jupiter’s, periodicity is over days. For our sun, might it be for over years, consistent with period of red dwarf companion?

Since approximately 1000 Jupiter masses equal mass of sun; thus for red dwarf of .04 solar mass, then ~40 Jupiter masses. Where would the center of gravity be, for such binary system? And what would motion for our sun look like, for such binary system? One could seemingly work both ways, deriving mass of system from doppler radial velocity effect; or conversely.

For movement of Sun, because of a binary companion for such system, one might consider a simplified circular motion; then would entire system (planets, asteroid belt, Kuiper belt, any neutrino belt, Oort cloud) all shift over a period of years (?), for a red dwarf binary companion with period of years? That is, most of mass (95% for our ex.) is associated with our sun; hence such motion of sun would have associated changing center of mass.

Would rate of parallax changing give period of such primary stellar motion? Also no adjustments to gravitational potential values for various objects’ locations, for system moving as a whole, for massive sun’s location. So no relative change for inside overall system; but for comparison to outside environment, sun’s change in location would have effect of gradual change in curvature. Not unlike a rogue black hole binary moving into our system?
