VizieR Online Data Catalog: OB stars in Cygnus OB2 association (Comeron+, 2012)
Abstract
By using reddening-free indices based on BJHK magnitudes from the USNO-B and 2MASS catalogs, we are able to produce a highly complete, highly uncontaminated sample of O and early B stars, which nearly duplicates any previous census of the region for the same range of spectral types. We provide the spectral types of 60 new O and B stars, as well as a list of an additional 60 candidates pending spectroscopic confirmation. In addition, the UBV imaging of the surroundings of three apparently isolated Ostars is used to investigate the possible presence of small clusters of young stars around them.
