Scientific paper

An analysis of 19 published radial-velocity measurements of the broad H I and He I lines during the period 1904-1979 indicates that Theta CrB may be a long-period spectroscopic binary with an orbital period of 510.87 days. It is shown that the time of a hypothetical primary eclipse predicted from the orbital solution agrees well with the 0.7-m deep photometric minimum observed by Roark (1971). Roark et al. (1972) proposed that the visual companion to Theta CrB (discovered by Couteau, 1971) is responsible for this light variation; it is argued in the present paper that this proposal is untenable. It is noted that the unusual disappearance of the C IV lines in the UV spectrum o Theta CrB (reported by Doazan et al., 1983) occurred at about the time of the predicted primary eclipse.
