标题： A High-resolution Spectrum of the R CrB Star V2552 Ophiuchi

摘要： 测光和低分辨率光谱学将V2552 Oph归入了罕见的北冕座R型变星类。我们通过比较这颗恒星以及R CrB和该类别的其他F型成员的高分辨率光学光谱，确认了这一分类。我们表明，V2552 Oph最类似于Y Mus和FH Sct，这些恒星中Sr、Y和Zr元素被增强。 显示英文摘要

摘要： 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.
