The Radial-Velocity Variation of Theta Ophiuchi.
Abstract
A rediscussion of Henroteau's 1920 and 1922 radial-velocity measurewents and new observations with the 82-inch McDonald telescope in February, 1955, show that 0 Ophiuchi very probably is a Canis Majoris star with a period of 0.153846 day The welocity, as well as the amplitude of the radial-velocity variation, is variable. A beat period of about 68 days is suspected
