Might hot jupiter`s inward migration to current assumed stable orbit serve as a model for the possibility of coalescing black holes?
Assuming a past 2-body interaction of gas giants, resulting in an additional vectorial component for subsequent inward spiraling hot jupiter; why would such inward spiraling cease?
Might it result from spin orbital dynamics, respectively for star and planet? Or is it when angular velocity becomes sufficient that one can consider as if one has centrifugal force off setting such inward migration? So not related to mass nor curvature. How would such model differ from inward spiraling black holes, and simulations thereof?
Would such scenario seem more likely than coalescence of mass, in principle (angular momentum/ centripetal problem?) as well as for simulations? Likewise then for consideration of merging of other massive objects, such as for NS-NS stars or BH-NS merging for GRB origin, or for hot Jupiter and star considered merger?
That is, does nature have a problem with such massive merger models; perhaps related to angular momentum and centrifugal force? Is this in turn related to larger theme that manifolds act as though they want to be left alone; that is, disjoint, then aways disjoint; and if intersecting, then always intersecting; and resistance to deformation?
So might a hot jupiter migratory model, and assumed current stable orbit, serve as an example of what might happen for black holes attempting to coalesce, as well as also representative of manifold behavior in general? TMM
