Tomographic Separation of Composite Spectra. IX. The Massive Close Binary HD 115071
We present the first orbital elements for the massive close binary HD 115071, a double-lined spectroscopic binary in a circular orbit with a period of 2.73135 ± 0.00003 days. The orbital semiamplitudes indicate a mass ratio of M2/M1 = 0.58 ± 0.02, and yet the stars have similar luminosities. We …
