HadV98 = V2552 Oph こういう研究が出ています。この天体の発見はかなり反響があったようです。 （IBVSに出した発見詳報の論文もよいタイミングだったようです） Paper: astro-ph/0308447 From: David Yong <tofu@astro.as.utexas.edu> Date: Mon, 25 Aug 2003 21:40:05 GMT (25kb) Title: A High-resolution Spectrum of the R CrB Star V2552 Ophiuchi Authors: N. Kameswara Rao (Indian Institute of Astrophysics, Bangalore, India), David L. Lambert (Department of Astronomy, University of Texas at Austin, USA) Comments: 10 pages, 3 figures, to appear in PASP Nov issue \\ 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. \\ ( http://arXiv.org/abs/astro-ph/0308447 , 25kb)
