"Probing the nearby universe with Massive Stars."

Miguel A. URBANEJA (Institute for Astro- and Particle Physics, University of Innsbruck)

Abstract

The quantitative spectroscopy of individual massive stars in galaxies provides, among other things, stellar chemical abundances, representing a more accurate constraint of the present-day metallicity of star forming galaxies than the widely used HII regions, which are significantly affected by systematic uncertainties not well understood. The combination of efficient multi-object spectrographs, sophisticated model atmosphere codes, and advanced analysis methods made individual massive stars in a significant volume of the local universe accessible to quantitative spectroscopy, including objects in galaxies well beyond the Local Group. In this talk, I will review how the field of “Extragalactic Stellar Astrophysics” has matured over the last 10 years, as well as present my particular view on the challenges and prospects for the future.
