Keplerian masses for the most massive stars: the very luminous, hydrogen-rich Wolf-Rayet stars
Abstract
We propose that the most massive stars in the local Universe start out on the main sequence being extremely luminous and already exhibiting wind-like emission lines. Such stars can probably be identified as hydrogen-rich WN5-7 stars. Masses are now being determined for these stars using the least model-dependent technique of binary orbits.
