One (pedantic) correction: objects more massive cannot be held up by neutron degeneracy pressure, but you can have more massive stars held up by radiation pressure from fusion. Certainly, there are many giant stars in the 2-8 solar mass range, and rarer stars in tens-to-hundreds of solar masses. Of course, they will eventually burn away their fusion fuel, and the core remnant may indeed become a black hole.
- pdonis 6y ago> you can have more massive stars held up by radiation pressure from fusion Radiation pressure actually isn't significant in the structure of most stars (it might be for huge stars near the Eddington limit). What holds up stars is ordinary thermal pressure due to the high temperatures inside them. The high temperatures are maintained by the fusion reactions in the stellar cores, yes. You're correct that objects like this do not have a maximum mass limit the way white dwarfs and neutron stars do.
