Resumen:
The strong stellar winds of massive O stars swept-up and compress the surrounding interstellar gas creating interstellar bubbles in their environs. In this modified environment, massive stars evolve into Luminous Blue Variables (LBVs), which are the immediate progenitors of WR stars. Using medium angular resolution radio surveys we investigate the presence of relic of interstellar bubbles originated in the stellar winds of the O-type progenitors of a number of galactic LBVs.
