Session 108 - The Galactic Stellar Disk & Halo.
Display session, Saturday, January 10
PG 1002+506 is found to be a Be star, one of two so far found by the Palomar-Green survey. Its spectrum is classified as a B5\pm 1 Ve, with T_eff = 14,900 \pm 1200, \log g = 4.2 \pm 0.2, and v \sin i = 340 \pm 50 km s^-1. At b = +51^\circ, its height above the Galactic plane would therefore be Z = +10.8 kpc, putting this apparently young, rapidly rotating star well into the Galactic halo. Its heliocentric radial velocity is found to be -2 \pm 15 km s^-1, consistent with either having been formed in the Galactic disk and subsequently ejected, or having been formed in the halo.
