The galactic WN7/WN8 stars as massive O stars in advanced stages of evolution
Published online by Cambridge University Press: 14 August 2015
Abstract
It is shown from various observational contraints that WN7/WN8 stars tend to occupy a class of their own set apart from other Wolf-Rayet subclasses. They probably evolved by stellar-wind mass loss from Of stars with original masses greater than ~35 m⊙, whether single or component of a binary. Two WN7/WN8 stars may be runaways in the second WR phase. One, HD 197406, is situated over 1000 pc from the galactic plane and has a low-mass, overluminous companion which is eclipsed by the WN7 component.
