The stellar populations of galaxies in the Local Group.
Abstract
Developments are examined on the star formation history of Local Group galaxie which is reflected in the HR diagrams, luminosity functions and integrated colors. The proposition that the bulk of star formation in the Large Magellanic Cloud occurred a few billion years ago is supported by five separate lines of evidence: the main sequence luminosity function, the subgiant branch, the horizontal branch, carbon stars, and the ages of star clusters. The dwarf spheroidal companions of the Milky Way, the bulge components of Local Group galaxies, and the spheroidal population of M31 and companions are considered.
