摘要: We discuss the reliability of stellar parameters derived from spectroscopic analyses with atmosphere models. follow revisions a WN4b star through improvements model codes carried out in last ten years. In order to judge current results we have started analyze binaries for which mass WR is known and therefore its luminosity can be theoretical mass-luminosity relation. Along this line, present preliminary work progress on binary γ2 Velorum.
