Astronomy Colloquium

Revealing Massive Star Mass Loss Through Supernovae
Takashi Moriya, Assistant Professor, NOA Japan,

Mass loss is one of the most uncertain factors in massive star evolution. Mass loss strongly affects the final fate of massive stars and proper knowledge of mass loss is crucial in understanding supernovae and their progenitors. Supernova explosions occur within the circumstellar media created by their progenitors' mass loss. The circumstellar media affect supernova properties, and it is possible to trace the mass-loss properties of massive stars through supernovae. In this talk, I will discuss how the circumstellar media affect the observational properties of supernovae. I will discuss mysterious mass loss of massive stars triggered shortly before their explosion that is revealed by identifying the signatures of the circumstellar media in supernovae.
