EVIDENCE FOR THE DUPLICITY OF THE ANOMALOUS CEPHEID Y OPHIUCHI

EVIDENCE FOR THE DUPLICITY OF THE ANOMALOUS CEPHEID Y OPHIUCHI

The mean velocity of this 17-day cepheid seems to show a variation due to binary motion with a period of 2612 days. Orbital elements are given. It is unlikely that the light of the companion is responsible for the small ranges in light, color, and radial velocity of the cepheid.
