The gamma Velorum binary system. II. WR stellar parameters and the photon loss mechanism
Orsola De Marco, W. Schmutz, P. A. Crowther +4
In this paper we derive stellar parameters for the Wolf-Rayet star in the gamma Velorum binary system (WR11), from a detailed non-LTE model of its optical and infrared spectra. Com…
