SPECTROSCOPIC ORBITAL ELEMENTS FOR A DOUBLE-LINED BINARY IN NGC 752

Orbital elements for a double-lined spectroscopic binary in the intermediate-age galactic cluster NGC 752 are reported. The binary is located just above the cluster main-sequence turnoff, and is a confirmed proper-motion and radial-velocity member. The equal amplitudes ofthe primary and the secondar...

Description
Summary:Orbital elements for a double-lined spectroscopic binary in the intermediate-age galactic cluster NGC 752 are reported. The binary is located just above the cluster main-sequence turnoff, and is a confirmed proper-motion and radial-velocity member. The equal amplitudes ofthe primary and the secondary velocity curves indicate that the stars have equal masses.
