Massive stars are known to have a profound impact on their surroundingsthrough their high ionizing radiation, their strong stellar winds, and their eventual finalexplosion as supernova. Within the area surveyed by the CGPS project there are 87 Otypestars and 36 galactic Wolf-Rayet stars. Therefore, the CGPS is an ideal databasetu study, in a large number of stellar targets, the interaction of massive stars (and itsdescendants) with their surroundings. In this paper we report on the study carried outtowards the massive stars HD 192281. A shell like structure, detectable at radio continuum,infrared and neutral hydrogen emissions, is found to be associated with thisstar.
