Thèse (PhD.)--Universidad Nacional Autónoma de México.
The most massive stars in the galaxy - those with more than 15 to 20 solar masses
- are lilkely to ionize their surroundings before they reach their final mass. How
can they accrete in spite of the presence of over-pressurized gas? This thesis presents
results of Submillimeter Array (SMA) and Very Large Array (VLA) studies of massive
star formation regions in the early stages of ionization, as well as an analysis of
numerical simulations of the evolution of these young HII regions. The results favor
a picture in which very massive stars form in accretion flows that are partially ionized
and that keep accreting material from their environment
