Scientific paper

Orbital elements are reported for the spectroscopic binary H110 (HD 11811), a giant star in the intermediate-age galactic cluster NGC 752. The center-of-mass velocity of the star is consistent with its membership in the cluster. Light from a mid-F dwarf companion can account for the unusual position of the star to the blue of the helium-burning clump.
