Orbits of two double-lined spectroscopic binaries HD 147971 and 75759
Abstract
HD 147971 (E Nor), discovered by the Lick observers over 50 years ago to show two spectra, consists of two B3 V stars. Orbital elements are derived for the first time (Table III). HD 75759 is a newly discovered binary system, consisting of two O9 V stars, with the long period of days and large eccentricity (Table VI). m1 sin3 i and m2 sin3 i are and respectively in the solution. The orbital elements are remarkably similar to those of L Ori and HD 37756. It is the central exciting source in a large H II region (Gum 17).
