Hunter, Deborah J., Valenti, Stefano, Kotak, Rubina, Meikle, Peter, Taubenberger, Stefan, Pastorello, Andrea, ...
We present photometric and spectroscopic observations at optical and near-infrared wavelengths of the nearby type Ic SN 2007gr. These represent the most extensive data-set to date of any supernova of...
Spectra and Light Curves of Failed Supernovae (2009)
Fryer, Chris L., Brown, Peter J., Bufano, Filomena, Dahl, Jon A., Fontes, Christopher J., Frey, Lucille H., ...
Astronomers have proposed a number of mechanisms to produce supernova explosions. Although many of these mechanisms are now not considered primary engines behind supernovae, they do produce...
Optical Spectroscopy of the Somewhat Peculiar Type IIb Supernova 2001ig (2009)
Silverman, Jeffrey M., Mazzali, Paolo, Chornock, Ryan, Filippenko, Alexei V., Clocchiatti, Alejandro, Phillips, Mark M., ...
Here we present previously unpublished optical spectra of supernova (SN) 2001ig, a Type IIb SN, from about a week after explosion until nearly one year later. The earliest spectrum consists of only a...
The He-rich core-collapse supernova 2007Y: Observations from X-ray to Radio Wavelengths (2009)
Stritzinger, Maximilian, Mazzali, Paolo, Phillips, Mark M., Immler, Stefan, Soderberg, Alicia, Sollerman, Jesper, ...
A detailed study spanning approximately a year has been conducted on the Type Ib supernova 2007Y. Imaging was obtained from X-ray to radio wavelengths, and a comprehensive set of multi-band...
A low energy core-collapse supernova without a hydrogen envelope (2009)
Valenti, Stefano, Pastorello, Andrea, Cappellaro, Enrico, Benetti, Stefano, Mazzali, Paolo, Manteca, Jose, ...
The final fate of massive stars depends on many factors, including mass, rotation rate, magnetic fields and metallicity. Theory suggests that some massive stars (initially greater than 25-30 solar...

The nuclear diversity of type Ia supernova explosions (2008)
Podsiadlowski, Philipp, Mazzali, Paolo, Lesaffre, Pierre, Han, Zhanwen, Förster, Francisco
Consistent estimates of (56)Ni yields for type Ia supernovae (2006)
Stritzinger, Maximilian, Mazzali, Paolo, Sollerman, Jesper, Benetti, Stefano
We present (56)Ni mass estimates for seventeen well-observed type Ia supernovae determined by two independent methods. Estimates of the (56)Ni mass for each type Ia supernova are determined from (1)...
Spectroscopy of the type Ia supernova SN 2002er: days -11 to +215 (2005)
Kotak, Rubina, Meikle, Peter, Pignata, Giuliano, Stehle, Matthias, Smartt, Steve, Benetti, Stefano, ...
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 a type Ia...
Circumstellar Interaction of Type Ia Supernova SN 2002ic (2004)
Nomoto, Ken'ichi, Suzuki, Tomoharu, Deng, Jinsong, Uenishi, Tatsuhiro, Hachisu, Izumi, Mazzali, Paolo
SN 2002ic is a unique supernova which shows the typical spectral features of Type Ia supernovae (SNe Ia) near maximum light, but also apparent hydrogen features that have been absent in SNe Ia. We...
A second glance at SN 2002ap and the M74 field with XMM-Newton (2003)
Soria, Roberto, Pian, Elena, Mazzali, Paolo
We have re-observed the field of M74 in January 2003 with XMM-Newton, 11 months after the X-ray detection of SN 2002ap. From a comparison of the two XMM-Newton observations we obtain more accurate...
Hypernovae and their Nucleosynthesis (2002)
Nomoto, Ken'ichi, Maeda, Keiichi, Umeda, Hideyuki, Ohkubo, Takuya, Deng, Jingsong, Mazzali, Paolo
We review the characteristics of nucleosynthesis in 'Hypernovae', i.e., core-collapse supernovae with very large explosion energies ($ \gsim 10^{52} $ ergs). The hypernova yields show the following...
