Description

The results of a search for H I bubbles around the 14 WR stars known in the section of the Galaxy between l = 302 deg and l = 312 deg are presented. The results disclose four additional H I bubbles, all around WR stars at Galactic latitudes higher than absolute value of b = 2 deg. This increases to eight the number of known neutral gas bubbles surrounding WR stars. The new H I voids are associated with the WR stars 52, 54, 57, and 61. The fact that no H I bubbles were found around WR stars close to the Galactic midplane is probably a selection effect. 29 refs
