The mass discrepancy problem in O stars of solar metallicity. Does it still exist?

Abstract

Using own and literature data for a large sample of O stars in the Milky Way, we investigate the correspondence between their spectroscopic and evolutionary masses, and try to put constraints on various parameters that might influence the estimates of these two quantities.
