Galactic Metallicity Gradients Derived from OB Stars

Katia Cunha

Abstract

The distribution of stellar abundances along the the Galactic disk is an important constraint for models of chemical evolution and galaxy formation. In this talk I will discuss the radial gradients of C, N, O, Mg, Al, Si, as well as S, from abundance determinations in young OB stars spanning a range in Galactocentric distances between 4.7 and 13.2 kpc.
