V532 Oph Is a New R Coronae Borealis Star
Abstract
V532 Oph has been found to be a member of the rare, hydrogen-deficient R Coronae Borealis (RCB) stars from new photometric and spectroscopic data reported in this article. The light curve of V532 Oph shows the sudden, deep, irregularly spaced declines characteristic of RCB stars. Its optical spectrum is typical of a warm (Teff ∼ 7000 K) RCB star, showing weak or absent hydrogen lines, C2 Swan bands, and no evidence for 13C. In addition, the …
