The ISM around WR 152 and WR 153ab
We analyzed the distribution of the interstellar matter in the environs of the WR stars WR152 and WR153ab, associated with ring nebulae in the Sh2-132 Hii region. Our study is based on radio data (continuum, Hi, and CO(1-0) observations) and images in the far and mid IR. We have detected the radio c...

ISM: ring nebulae Stars: individual (WR152, WR153AB) Stars: wolf-rayet We analyzed the distribution of the interstellar matter in the environs of the WR stars WR152 and WR153ab, associated with ring nebulae in the Sh2-132 Hii region.

The distributions of the ionized and molecular gas related to WR153ab and that of the PAHs suggest the presence of photodissociation regions at the interface between the ionized and molecular material.
