NED Abstract

Copyright by Central Bureau for Astronomical Telegrams. 2005CBET..193A...1W Electronic Telegram No. 193 Central Bureau for Astronomical Telegrams INTERNATIONAL ASTRONOMICAL UNION SUPERNOVAE 2005de AND 2005df L. Wang, Lawrence Berkeley National Laboratory; and D. Baade, European Southern Observatory (ESO), report that SN 2005de and SN 2005df were observed on Aug. 6 using the ESO Very Large Telescope (+ FORS1) in spectropolarimetry mode. The spectroscopic data show that both SN 2005de and SN 2005df are type-Ia supernovae, about a week before optical maximum. The Ca II infrared triplets show a two-component structure very similar to SN 2001el (Wang et al. 2003, Ap.J. 591, 1110). The bluer components are much stronger than their redder counterparts; the minima of the bluer components are at velocities of about 20000 km/s.
