Observations of southern Wolf-Rayet stars - I: The spectroscopic binary HD 90657
The Wolf-Rayet star HD 90657 is found to be a spectroscopic binary with a WN5+O6 spectrum and a period of 6.456 days. Preliminary orbital elements show an elliptic orbit and a mass ratio MWR/Mo∼0.5. Evidence is presented for the Wolf-Rayet atmosphere being accelerated outwards and not being spherica...
