| Abstract: |
To improve our knowledge of O stars, their evolution, and
physical processes associated with O stars and their descendants,
it is crucial that we have reliable determinations of fundamental parameters,
abundances, and mass-loss rates. Unresolved issues include
discrepancies between evolutionary and spectroscopic masses, limitations in the
accuracy with which we can determine effective temperatures, surface gravities, and
abundances, and problems in mass-loss rate determinations. We address these
issues and their causes. |
