Supernova 2008cv in ESO 598-G22

Abstract

R. Chornock, W. Li, J. S. Bloom, A. A. Miller, D. A. Perley, J. H. Shiode, and A. V. Filippenko, University of California, Berkeley, report that inspection of CCD spectra (range 310-920 nm) obtained with LRIS on the Keck I 10-m telescope on June 7.6 UT reveals that 2008cv (CBET 1394) is a type-Ia supernova a few weeks after maximum brightness. The presence of an absorption trough near 420 nm attributed to Ti II indicates that the object may be subluminous, of the supernova-1991bg variety (Filippenko et al. 1992, A.J. 104, 1543).
