摘要：
Studies of the visually brightest stars, A- and B-type supergiants, in the Local Group galaxies M31 and M33 have been undertaken with HIRES on the 10-m Keck I telescope. Detailed chemical, element abundances are derived from these spectra (as reviewed at this conference by Venn); in this paper, we discuss the Keck observing program and the analysis of the H alpha line profile used to determine the stellar wind momentum. The current status of our tests of the Wind-momentum-Luminosity Relation in M31 and M33 is briefly summarized.
