18 de ene. de 2024 · Science. 19 Jan 2024. Astrophysical compact objects come in two varieties: neutron stars and black holes. Created when massive stars die and their cores collapse, neutron stars consist of protons and neutrons, whereas black holes are too heavy and dense to be described by anything other than gravity. These entities have uncertain mass limits.
