Resumen:
The strong stellar winds of massive O stars sweep up and compress the surroundinggas creating interstellar bubbles in their environs. In this modified environment, massivestars evolve into Luminous Blue Variables (LBVs), which are the immediate progenitorsof WR stars. Using the Canadian Galactic Plane Survey (CGPS) and Southern GalacticPlane Survey (SGPS) we searched for Hi interstellar bubbles associable with O-typeprogenitors of a number of galactic LBVs and LBV candidates. We found Hi cavities andshells that probably originated from the massive progenitors of P Cygni, G79.29+0.46,AG Carinae, and He3-519.
