Abstract (from CDS):

We present multiobject spectroscopy of young, massive stars in the Local Group galaxy IC 1613. We provide the spectral classification and a detailed spectral catalog for 54 OBA stars in this galaxy. The majority of the photometrically selected sample is composed of B- and A-type supergiants. The remaining stars include early O-type dwarfs and the only Wolf-Rayet star known in this galaxy. Among the early B stars we have serendipitously uncovered six Be stars, the largest spectroscopically confirmed sample of this class of objects beyond the Magellanic Clouds. We measure chemical abundances for nine early B supergiants, and find a mean oxygen abundance of 12+log(O/H)=7.90±0.08. This value is consistent with the result we obtain for two H II regions in which we detect the temperature-sensitive [O III] λ4363 auroral line.
