The orbit of the double-lined Wolf-Rayet binary HDE 318016 (=WR 98).

GAMEN R.C. and NIEMELA V.S.

Abstract (from CDS):

We present the discovery of OB type absorption lines superimposed to the emission line spectrum and the first double-lined orbital elements for the massive Wolf-Rayet binary HDE 318016 (=WR 98), a spectroscopic binary in a circular orbit with a period of 47.825 days. The semiamplitudes of the orbital motion of the emission lines differ from line to line, indicating mass ratios between 1 and 1.7 for MWR/MOB.
