Dark star, magnetic ‘fields’ i.e. density; and conjectures

Might Jupiter’s internal temperature be higher than the sun’s; hence somewhat less organized circulation and current flow? But Jupiter’s magnetic field is stronger than the sun’s. Both have angular momentum.

Might jovian moons’ rheology be that of an ocean and/or slush; but organized circulation / current flow? Do brown dwarfs and red dwarfs, with possible hotter fission reactors, have a magnetic field; or might greater heat of fission result in a more disorganized current flow? Do all stars have a magnetic  density region i.e. ‘field’ ?

Might counter rotation of earth’s solid core serve as a model of a conductor’s rotation in a changing magnetic field? Hence perhaps a jovian solid core rotating conductor commenced it’s formative rotation as a result of a changing magnetic field. Would rotational sense just be fortuitous, based on such changing magnetic field; likewise for earth’s core rotation sense?

Other than our sun’s fusion reactor, have magnetic fields been detected for other stars? Based upon jovian moons, apparently not just a plasma current would be necessary for a magnetic field. Could Jupiter have a charged current (possible for liquid hydrogen core?); but how could one have a charged current in such liquid? Even if our sun has a liquid core, then still a gaseous fluid, with charged current, would seem necessary; with the above partial exception of some jovian moons?

Does a ‘dark star (i.e. black hole) have a corona; and an external magnetic field? Hence an organized internal current (plasma flow; for example, with at least a recombinant temperature as a minimum, for hydrogen ionization?), together with internal/external magnetic field? Thus consistent with an internal circulation; also angular momentum seems consistent with some sort of internal circulation. Is there any reason why a dark star might not have some ongoing fusion/ fission for gaseous/ liquid phase process? Would the latter place any additional constraints on a black hole construct; or just additional heat?

The extremes of  energy (4B solar masses in a seemingly small volume of ~2000 km diameter for galactic BH? Recombination temperature would be the minimum, and hence maximum volume, for ionized hydrogen. Wouldn’t thermodynamics and entropy then seem to predominate; thus energy being re-distributed out of such higher density? For example, is there ~ homogeneous distribution of energy, with episodic jet outbursts? Or is there a more central heterogeneous turbulent chaotic mixing?

Might any disruption of an internal organized plasma current affect an internal/external magnetic field, and hence disrupt any radio emission? If radio detection were significant for Sagittarius A* at such distance, and if it is related to a non-visible jet from the geometric center of orbiting objects (merged dwarf galaxies?  see early universe, and physical truth), over a longer period of time, might there be any substantial change in such radio emission; hence change in internal plasma current? Might a dark star, and environs, with inflowing plasma to polar region, together with magnetic fields, generate a directional radio emission, somewhat similar to Jupiter’s non-directional broadcast like signal? Might this perhaps serve as a possible model, relating to radio source – Sagittarius A*, wherein such radio source is supposedly localized to less than Mercury’s orbital radius (.3 -.46 AU)? Hence is such dark star, with plasma flow into polar region, together with magnetic field, consistent with a directional radio emission?

How close is geometric center from trajectory of alleged 6 orbiting objects (dwarf galaxies, or M32 like?), to Sagittarius A* radio source? Or might the latter radio source be, for example, from an in apparent jet interacting with more distant matter? If M87 jet were relocated to our galactic center, would it be too large (2000x ?) and too close to be seen? Or would increased luminosity ~ squared, dominate? Would background stars be obscured? If galactic black hole is of a comparatively small volume (<2000 km, for example), then even with substantial matter inflow, and also in orbit or in the vicinity, one would seemingly not expect to see anything.  TMM* A.
