Splinter Session D - AG Meeting 2014 Bamberg


Eta Car Abell 30

Abstract

The population of hot stars is very diverse, ranging from young massive main sequence stars, giants and supergiants to old and evolved objects like white dwarfs and their immediate progenitors. Studying those stars helps us to understand key problems of stellar astrophysics like the formation of massive stars, close binary interactions, radiation-driven winds, and the final stages of stellar evolution. Solving these problems is central to our understanding of related issues like supernovae, with important implications for cosmology, and the history of chemical enrichment in galaxies. Although considerable progress has been made in the last decade, analysing hot stars remains challenging, because peculiar chemical compositions, NLTE effects, mass-loss, rotation, variability, and binarity have to be taken into account. Trying to make sense out of the observational evidence makes us aware of the shortcomings in stellar evolution models.

This splinter meeting aims at bringing together the hot star community, both observers and theorists, for giving the opportunity to present recent contributions to the field and to discuss the open issues. We would like to invite you to contribute both oral and poster presentations. The deadline for abstract submission is 18 August 2014.
