Say a core collapse event of a massive star occurs, forming neutron star matter in its core. However, the explosion manages to eject enough core mass such that the remnant is below the Chanrasehkar limit. At this point, gravity would no longer be able to overcome electron degeneracy pressure, decreasing the density, so wouldn't the star's material return to some atomic state? What would be the properties of such a star? Or another question, if a 1.3 Ms white dwarf can be composed entirely of atomic matter, then shouldn't a 1.3 Ms (at least former) neutron star be composed of atomic matter as well?
