  • Context. The “mass discrepancy” in massive O stars represents a long-standing problem in stellar astrophysics with far-reachin g implications for the chemical and dynamical feedback in galaxies. Aims. Our goal is to investigate this mass discrepancy by comparing state-of-the-art model masses with model-independent masses determined from eclipsing binaries. Methods. Using stellar evolution models and a recent calibration of stellar parameters for O-star spectral sub-classes, we pres ent a… CONTINUE READING
