Comparing Chemical Abundances of the Damped Lyα Systems and Metal-Poor Stars
I briefly draw comparisons between the fields of damped Lya and metal-poor stellar abundances. In particular, I examine their complementary age-metallicity relations and comparisons between the damped Lya and dwarf galaxy abundance patterns. Regarding the latter, I describe a series of problems concerning associating high z damped Lya systems with present-day dwarfs.
