Late evolution of stripped-envelope supernova progenitors

Stripped-envelope and ultra-stripped-envelope supernovae mark the deaths of massive stars that have lost their outer layers. Several physical mechanisms have been proposed to explain the formation and properties of stripped-envelope stars, including wind mass loss and binary mass transfer. In addition, many stripped-envelope supernovae show evidence for interactions with circumstellar material, indicating that these mass-loss processes take place, at least in part, in the latest stages of the evolution, shortly before the supernova explosion.

In this talk, I will give an overview of the evolution of possible progenitors of stripped-envelope supernovae. In particular, I will focus on the late stages of the evolution. Finally, I will review the possible origins of circumstellar material and discuss what is needed to better understand the progenitors of these supernovae.
