| Abstract: |
This paper is a review and an update on recent work on the physical and chemical structure of the envelopes of newly born massive stars, at the stages preceding ultracompact HII regions. It discusses methods and results to determine total mass, temperature and density structure, ionization rate, and depth-dependent chemical composition. |
