New O-type stars in the LAMOST Data Release 3.

ROMAN-LOPES A. and ROMAN-LOPES G.F.

Abstract (from CDS):

In this paper, we present a sample of 27 new Galactic O-type stars found in the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) Data Release 3 (DR3). The new O-stars were identified by visual examination of spectra in a subsample of the main DR3 catalogue. The earliest of these new Galactic O-stars are two O4 stars: LS V +39 27, an O4 V((f)) star placed in the Outer Arm, probably at more than 15 kpc from the centre of the Galaxy; 2MASS J20261845+4347472, an O4 IV(f) star that has not previously been identified as OB-type. Taking into account the number of new O-stars found in the LAMOST DR3, it is very likely that more will be discovered/identified in the future. Indeed, about 63 per cent (18 of 27) of the new O-type stars are bright sources (V = 12), indicating that an important fraction of the Galactic O-stars is still unidentified, waiting to be catalogued/classified from large Galactic surveys such as LAMOST.
