Stellar astrophysics in the local group and beyond with the GTC
Revista Mexicana de Astronomia y Astrofisica: Serie de Conferencias 16 (2003) 145-149
Abstract:
In this review I discuss the capabilities that the GTC, and in particular the OSIRIS spectrometer, will bring to studying massive stellar populations within Local Group galaxies and even beyond. By observing massive stars in other dwarf irregular and spiral galaxies one can probe star formation and stellar evolution in extreme environments, the wind properties of massive luminous stars, and determine distances to an accuracy of ∼10%.Theory of Pixel Lensing toward M31.
