A radial velocity study of the chemically peculiar B star Theta Carinae.
Abstract
A period of 1.7788 days has been found for radial-velocity and line-strength variations in the spectrum of the peculiar B star Theta Car. The star is evidently a single-lined spectroscopic binary with a relatively low-mass companion. Mass transfer in the system could possibly provide an explanation for the spectral anomalies as well as for the singular location of Theta Car in the H-R diagram of the young cluster IC 2602. HR 3147 in NGC 2516 may be a similar object.
