Stellar Winds and Mass Loss

Sternwinde und Massenverlust, MVSpec

Sommersemester 2022

The mass is a fundamental quantity of stars that decides their life and fate. In the last decades, it has become clear that the mass of a star is not only set by its initial conditions, but can significantly change during the life of the star. In this lecture, which will be intertwined with some instructive excercises, we will discuss why stars can lose mass and which mechanisms play are role here. A particular focus will be to provide an overview of the various types of stellar winds we find in different types of stars and their physical origin. After exploring the different wind regimes (solar wind, hot stars, cool stars), the lecture will also cover the consequences of strong mass outflow on the evolution and environment of stars.

Target audience: Master students with at least a basic knowledge about astrophysics and an interest in stellar winds and their impact.

Oberseminar: Hot Stars
