A High-resolution Spectrum of the R CrB Star V2552 Ophiuchi
arXiv:astro-ph/0308447 · doi:10.1086/379205
Abstract
Photometry and low-resolution spectroscopy have added V2552 Oph to the rare class of R Coronae Borealis variables. We confirm this classification of V2552 Oph through a comparison of our high-resolution optical spectrum of this star and that of R CrB and other F-type members of the class. We show that V2552 Oph most closely resembles Y Mus and FH Sct, stars in which Sr, Y, and Zr are enhanced.
