Massive stars are the dominant population in star-forming galaxies, driving their evolution via intense radiation fields and feedback from their winds and supernova explosions. Only by improving our models of stellar evolution via empirical studies in the local Universe can we hope to achieve a realistic interpretation of unresolved populations in distant galaxies.
Recent work in the Milky Way and Magellanic Clouds has led to important new insights in our understanding of massive stars, such as revision of the upper-mass limit to the IMF, the incidence of multiplicity, the effects of metallicity, and the role of rotational mixing in their atmospheres. In parallel to these efforts, spectroscopy of luminous massive stars in galaxies at Mpc distances has been used to obtain direct chemical abundances, tracing the star-formation history and chemical evolution of their host galaxies. We invite talks for two sessions on topics related to massive star evolution, supernova progenitors, and extragalactic massive stars.
