The Origin and Evolutionary Status of B Stars Found Far From The Galactic Plane

John C. Martin, Case Western Reserve Universtiy

A poster presented at the 2003 Winter American Astronomical Society Meeting in Seattle, WA


Summary

The spectroscopic abundances and kinematics of a sample of faint B stars far from the galactic plane and appearing at the low spectroscopic dispersions to be Population I stars, were analyzed to determine their nature and origin. Out of 49 stars: 26 are identified as Population I stars that have been ejected from the galactic disk, 18 are evolved sub dwarfs, and 5 remain unclassified. There are no stars in the sample that appear to be Population I stars which formed in situ in the galactic halo.
