WSRT 21-cm continuum field in Cygnus OB2: in search of more Wolf-Rayet stars∗
Published online by Cambridge University Press: 25 May 2016
Abstract
We present a deep look into the Cygnus OB2 region using the WSRT. A 2° x 2° map of the optically highly-obscured region was obtained at 1400 MHz, with a noise level down to 0.2 mJy and an angular resolution of 1″. We will compare the resulting radio point source list with optical and near-IR catalogues, in order to identify stellar wind sources like WR and OB stars.
