Staring at a very dim X-ray binary

Some neutron stars that consume gas from a companion star generate much dimmer X-rays than the general population of X-ray binaries. Since the brightness scales with the amount of mass that is being devoured, it seems that in these… 440 more words


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? 922 more words
