Spectroscopy of the Type Ia supernova 2011fe past 1000 days
S. Taubenberger, N. Elias-Rosa, W. E. Kerzendorf +11
In this letter we present an optical spectrum of SN 2011fe taken 1034 d after the explosion, several hundred days later than any other spectrum of a Type Ia supernova (disregarding…
Photometric and spectroscopic observations, and abundance tomography modelling of the type Ia supernova SN 2014J located in M82
C. Ashall, P. Mazzali, D. Bersier +5
Spectroscopic and photometric observations of the nearby Type Ia Supernova (SN Ia) SN 2014J are presented. Spectroscopic observations were taken -8 to +10 d relative to B-band maxi…
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…
Exploring the spectroscopic diversity of Type Ia Supernovae
S. Hachinger, P. A. Mazzali, S. Benetti
The velocities and equivalent widths (EWs) of a set of absorption features are measured for a sample of 28 well-observed Type Ia supernovae (SN Ia) covering a wide range of propert…
Massive stars exploding in a He-rich circumstellar medium. V. Observations of the slow-evolving SN Ibn OGLE-2012-SN-006
A. Pastorello, L. Wyrzykowski, S. Valenti +36
We present optical observations of the peculiar Type Ibn supernova (SN Ibn) OGLE-2012-SN-006, discovered and monitored by the OGLE-IV survey, and spectroscopically followed by PESS…
Nebular spectra and abundance tomography of the type Ia supernova SN 2011fe: a normal SN Ia with a stable Fe core
P. A. Mazzali, M. Sullivan, A. V. Filippenko +10
A series of optical and one near-infrared nebular spectra covering the first year of the Type Ia supernova SN 2011fe are presented and modelled. The density profile that proved bes…
