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… Expand
Spectroscopic and physical parameters of Galactic O-type stars. III. Mass discrepancy and rotational mixing
Context. Massive stars play a key role in the evolution of galaxies and our Universe. Aims. Our goal is to compare observed and predicted properties of single Galactic O stars to identify andExpand
On the consistent treatment of the quasi-hydrostatic layers in hot star atmospheres
CONTEXT: Spectroscopic analysis remains the most common method to derive masses of massive stars, the most fundamental stellar parameter. While binary orbits and stellar pulsations can provide muchExpand
The Spectroscopic Hertzsprung–Russell Diagram of Hot Massive Stars in the Small Magellanic Cloud
We present a comprehensive stellar atmosphere analysis of 329 O- and B-type stars in the Small Magellanic Cloud (SMC) from the RIOTS4 survey. Using spectroscopically derived effective temperatureExpand
Massive star evolution revealed in the Mass-Luminosity plane
Abstract Massive star evolution is dominated by key physical processes such as mass loss, convection and rotation, yet these effects are poorly constrained, even on the main sequence. We utilise aExpand
Predictions for mass-loss rates and terminal wind velocities of massive O-type stars
Context. Mass loss from massive stars forms an important aspect of the evolution of massive stars, as well as for the enrichment of the surrounding interstellar medium. Aims. Our goal is to predictExpand
A quantitative study of O stars in NGC 2244 and the Monoceros OB2 association
Aims. Our goal is to determine the stellar and wind properties of seven O stars in the cluster NGC 2244 and three O stars in the OB association Mon OB2. These properties give us insight into the massExpand
TOWARD A UNIFICATION OF STAR FORMATION RATE DETERMINATIONS IN THE MILKY WAY AND OTHER GALAXIES
The star formation rate (SFR) of the Milky Way remains poorly known, with often-quoted values ranging from 1 to 10 Myr −1 . This situation persists despite the potential for the Milky Way to serve asExpand
Mass-loss rates from mid-infrared excesses in LMC and SMC O stars
We use a combination of BVJHK and Spitzer [3.6], [5.8] and [8.0] photometry to determine infrared (IR) excesses for a sample of 58 Large Magellanic Cloud and 46 Small Magellanic Cloud O stars. ThisExpand
Empirical Properties of Very Massive Stars
In this chapter we present the properties of the most massive stars known by the end of 2013. We start with a summary of historical claims for stars with masses in excess of several hundreds, evenExpand
Massive star evolution: rotation, winds, and overshooting vectors in the mass-luminosity plane
Context. Massive star evolution is dominated by various physical effects, including mass loss, overshooting, and rotation, but the prescriptions of their effects are poorly constrained and evenExpand
