Optical and IR observations of SN 2002dj: some possible common properties of fast expanding SNe Ia
G. Pignata, S. Benetti, P. A. Mazzali +17
As part of the European Supernova Collaboration we obtained extensive photometry and spectroscopy of the type Ia SN 2002dj covering epochs from 11 days before to nearly two years a…
The early spectral evolution of SN 2004dt
G. Altavilla, M. Stehle, P. Ruiz-Lapuente +18
Aims. We study the optical spectroscopic properties of Type Ia Supernova (SN Ia) 2004dt, focusing our attention on the early epochs. Methods. Observation triggered soon after the S…
Anomalous extinction behaviour towards the Type Ia SN 2003cg
N. Elias-Rosa, S. Benetti, E. Cappellaro +14
We present optical and near-infrared photometry and spectroscopy of the Type Ia SN 2003cg, which exploded in the nearby galaxy NGC 3169. The observations cover a period between -8.…
Spectroscopy of the type Ia supernova SN 2002er: days -11 to +215
Rubina Kotak, Peter Meikle, Giuliano Pignata +8
We present an extensive set of optical spectroscopy of the nearby type Ia supernova, SN 2002er, with 24 epochs spanning -11 to +34 days. Its spectral evolution is fairly typical of…
High velocity features in the spectra of the Type Ia SN 1999ee: a property of the explosion or evidence of circumstellar interaction?
P. A. Mazzali, S. Benetti, M. Stehle +5
The near-maximum spectra of the Type Ia SN 1999ee are reviewed. Two narrow absorption features corresponding to the strongest component of the CaII IR triplet appear in the spectra…
Photometric Observations of the Type Ia SN 2002er in UGC 10743
G. Pignata, F. Patat, S. Benetti +20
Extensive light and colour curves for the Type Ia supernova SN 2002er are presented as part of the European Supernova Collaboration. We have collected UBVRI photometry from ten dif…
