White dwarfs, neutron stars, and black holes are the compact remnants that are the endpoints of stellar evolution. Although nuclear processes have stopped in these objects, they each continue to evolve in ways that are unique to their structure. As white dwarfs cool and become more degenerate, their baryon structure changes, altering their cooling process. Neutron stars are frequently born with high magnetic fields that slowly decay and spin down the neutron star. Black holes, however, will not change much for eons. In this chapter, we will look at the properties and continued evolution of these exotic objects.
