Galactic O-type stars in LAMOST data

Abstract

This paper reports 209 O-type stars found with LAMOST. All 135 new O-type stars discovered so far with LAMOST so far are given. Among them, 94 stars are firstly presented in this sample. There are 1 Iafpe star, 5 Onfp stars, 12 Oe stars, 1 Ofc stars, 3 ON stars, 16 double-lined spectroscopic binaries, and 33 single-lined spectroscopic binaries. All O-type stars are determined based on LAMOST low-resolution spectra (R ~ 1800), with their LAMOST median-resolution spectra (R~7500) as supplements.
