Massive stars exploding in a He-rich circumstellar medium. VI. Observations of two distant Type Ibn supernova candidates discovered by La Silla-QUEST
A. Pastorello, E. Hadjiyska, D. Rabinowitz +31
We present optical observations of the peculiar stripped-envelope supernovae (SNe) LSQ12btw and LSQ13ccw discovered by the La Silla-QUEST survey. LSQ12btw reaches an absolute peak…
A metric space for type Ia supernova spectra
Michele Sasdelli, W. Hillebrandt, G. Aldering +43
We develop a new framework for use in exploring Type Ia Supernova (SN Ia) spectra. Combining Principal Component Analysis (PCA) and Partial Least Square analysis (PLS) we are able…
OGLE-2013-SN-079: a lonely supernova consistent with a helium shell detonation
C. Inserra, S. A. Sim, L. Wyrzykowski +31
We present observational data for a peculiar supernova discovered by the OGLE-IV survey and followed by the Public ESO Spectroscopic Survey for Transient Objects. The inferred reds…
PESSTO monitoring of SN 2012hn: further heterogeneity among faint type I supernovae
S. Valenti, F. Yuan, S. Taubenberger +24
We present optical and infrared monitoring data of SN 2012hn collected by the Public ESO Spectroscopic Survey for Transient Objects (PESSTO). We show that SN 2012hn has a faint pea…
Constraining Type Ia supernova models: SN 2011fe as a test case
F. K. Roepke, M. Kromer, I. R. Seitenzahl +42
The nearby supernova SN 2011fe can be observed in unprecedented detail. Therefore, it is an important test case for Type Ia supernova (SN Ia) models, which may bring us closer to u…
