Distant field blue horizontal branch stars and the mass of the Galaxy - II. Photometry and the spectroscopy of UKST candidates 16

Clewley, Lee; Warren, S J; Hewett, Paul C; Norris, John; Evans, N W

Description

This is the second in a series of papers presenting a new calculation of the mass of the Galaxy based on radial velocities and distances for a sample of faint 16 < B < 21.3 field blue horizontal-branch (BHB) stars. We present accurate BV CCD photometry and spectra for 142 candidate A-type stars selected from ubjr photometry of UK Schmidt telescope plates in six high-Galactic-latitude fields. Classification of these candidates produces a sample of 60 BHB stars at distances of 11-52 kpc from the...[Show more]
