Scientific paper

Orbital elements are presented for the spectroscopic binary 26 Comae Berenicis, a late-type giant star near the North Galactic Pole. The elements were derived from 48 radial velocity measurements obtained over the period April 1973 to January 1980, primarily with the photoelectric radial-velocity spectrometer at Cambridge Observatory. A highly eccentric orbit and a period of 972 days are noted, along with a mass function suggesting that the unseen secondary may be a lower-main-sequence star or a white dwarf.
