Probing the Type Ia environment with Light Echoes
F. Patat
In general, Light Echoes (LE) are beautiful, rather academical and therefore unavoidably useless phenomena. In some cases, however, they can give interesting information about the…
ESC Observations of SN 2002er around Maximum Light
G. Pignata, F. Patat, R. Kotak +3
We present preliminary results of the observational campaign on SN 2002er carried out by the European Supernova Collaboration (ESC). For this supernova the optical coverage from ep…
Explosive Nucleosynthesis in Aspherical Hypernova Explosions and Late Time Spectra of SN1998bw
K. Maeda, T. Nakamura, K. Nomoto +3
Aspherical explosion models for the hypernova (hyper-energetic supernova) SN 1998bw are presented. Nucleosynthesis in aspherical explosions is examined with a two-dimensional hydro…
The Properties of Hypernovae: SNe Ic 1998bw, 1997ef, and SN IIn 1997cy
K. Nomoto, P. A. Mazzali, T. Nakamura +6
We discuss the properties of the hyper-energetic Type Ic supernovae (SNe Ic) 1998bw and 1997ef and Type IIn supernova (SN IIn) 1997cy. SNe Ic 1998bw and 1997ef are characterized by…
SNIa light curves and radioactive decay
E. Cappellaro, P. A. Mazzali, S. Benetti +4
The absolute V light curves of 5 SNe Ia, selected to represent the known range of absolute luminosities at maximum for this class of objects, are presented. Comparison of the long…
Revised photometry and color distribution of Type Ia supernovae observed at Asiago in the seventies
F. Patat, R. Barbon, E. Cappellaro M. Turatto
Following recent claims regarding possible errors in the photometry of SNe carried out at Asiago observatory during the 70's, which produced very blue color at maximum for…
