Description

Based upon a study of the distribution of the interstellar H I 21-cm-line emission around the Wolf Rayet star HD 156385, the presence of a remarkable expanding H I bubble, radio-counterpart of the optical nebula RCW 114, has been discovered which is surrounded by a thick H I shell. Both the H I and optical features display outstandingly similar morphologies, and have been created by the action of the strong stellar wind of the WR star and its massive progenitor. The H I bubble has a radius of 57 pc, an expansion velocity of 10 km/s, and a swept-up H I mass of 6300 solar masses. 33 references
