12CO (J=1-0) images of the surroundings of three galactic Wolf-Rayet stars

Abstract

We present 12CO (J=1-0) images of the surroundings of three galactic Wolf-Rayet stars. As part of a program aim to study the interaction of massive stars with their enviroments, we have begun a study of the distribution of molecular gas around Wolf-Rayet stars. The carbon monoxide database is combined with both far infrared (MSX and IRAS) and radio continuum observations at 2.4 and 5.0 GHz. A few cavities and arc-shaped structures were found likely to be associated with the Wolf-Rayet stars.
