Emmy Noether Research Group on Stellar Atmospheres and Mass Loss

Welcome to the former group website of the Emmy Noether research group on stellar atmospheres and mass loss of hot stars. We are in the process of moving to the Christian-Albrechts-Universität zu Kiel (CAU) with more information following soon.

Located at the conjuction of observation, theory and numerical astrophysics, our research focuses around the application and development of stellar atmosphere models to uncover the life and fate of hot stars and their winds. A particular emphasis of the group is the research on hot massive stars. With their high luminosity, these stars are major building blocks of galaxies as they dominate their surrounding with their strong stellar winds and their ionizing radiation. As production sites of heavy elements, massive stars also act as engines of the cosmic chemical evolution. By performing quantitative spectroscopy, simulating their winds, and providing predictions for their apperance and feedback, our group aims to uncover more about the enigmatic role of hot and massive stars in our Universe.

Members who are not yet in Kiel can be found at the Astronomisches Rechen-Institut (ARI) which is a part of the Zentrum für Astrophysik der Universität Heidelberg (ZAH).
