321D modelling of the evolution, nucleosynthesis and fate of massive stars

Massive stars play a key role in the Universe through the light they shine, the chemical elements they produce and the supernova explosions that mark their death. They leave remnants (neutron stars or black holes) that can later merge and emit gravitational waves (GW), which we can now detect with detectors such as LIGO and Virgo. In this talk, I will review the properties and evolution of massive stars and present theoretical predictions for their fate and the remnant they produce across cosmic times. I will also discuss the prospect of detecting rare supernova types and the key uncertainties affecting theoretical predictions. Finally, I will review the expected and unexpected nucleosynthesis taking place in the late phases of their evolution.
