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 B 5 \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 .
