		| 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. |
