Abstract

When massive stars end their life they can become either a neutron star or black hole. In this talk, we go through the basic concepts in astrophysics which allow us to understand the fate of these massive stars. We start by defining what is a star. We then describe the evolution of a star until death and how to determine what will its remnant be. Finally, we comment on an alternative model, the pair-instability supernova, which leaves no remnant at all.
