Contents Introduction to the Scientific Problem -- A MSFR at the Onset of Ionization: W33A -- A MSFR with Young UC and HC HII Regions: G20.08N -- Time Variability of HII Regions: A Signature of Accretion? -- Time Variability of HII Regions in Numerical Simulations of MSFR -- Conclusions
Summary 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
