Mass-loss rate predictions for hot stars (GA205/08/0003)

Massive hot stars constitute an important part of our Galaxy and many other galaxies. Consequently, a detailed knowledge of their evolution and of their influence on the circumstellar environment is necessary for our understanding of the structure an...

Hot star winds solving uncertainties of mass loss near the Eddington limit (GA25-15910S)

. To understand these processes, a detailed knowledge of the amount of mass lost per unit of time (mass-loss rate) is needed. However, such information is missing for luminous-of-the-art codes. We will provide precise m...
