Munich Hot Star Working Group

The main focus of the working group is the investigation of Hot Stars, particularly with regard to their moving atmospheres or stellar winds. The primary objective with respect to that are model simulations and the computation of synthetic spectra for O/B Stars, Central Stars of Planetary Nebulae and Supernovae.

For an introduction in the basic theoretical and diagnostical tools of expanding atmospheres, and their application in a broad astrophysical context accumulated over the last 20 years see the latest reviews:
