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…
PESSTO : survey description and products from the first data release by the Public ESO Spectroscopic Survey of Transient Objects
S. J. Smartt, S. Valenti, M. Fraser +99
The Public European Southern Observatory Spectroscopic Survey of Transient Objects (PESSTO) began as a public spectroscopic survey in April 2012. We describe the data reduction str…
Supersolar Ni/Fe production in the Type IIP SN 2012ec
Anders Jerkstrand, Stephen J. Smartt, Jesper Sollerman +14
SN 2012ec is a Type IIP supernova (SN) with a progenitor detection and comprehensive photospheric-phase observational coverage. Here, we present Very Large Telescope and PESSTO obs…
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…
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…
Optical and Ultraviolet Observations of A Low-Velocity Type II-Plateau Supernova 2013am in M65
Jujia Zhang, Xiaofeng Wang, Paolo A. Mazzali +16
Optical and ultraviolet observations for the nearby type II-plateau supernova (SN IIP) 2013am in the nearby spiral galaxy M65 are presented in this paper. The early spectra are cha…
Abundance stratification in Type Ia Supernovae - IV: the luminous, peculiar SN 1991T
Michele Sasdelli, Paolo A. Mazzali, Elena Pian +4
The abundance distribution of the elements in the ejecta of the peculiar, luminous Type Ia supernova (SN Ia) 1991T is obtained modelling spectra from before maximum light until a y…
Bolometric light curves and explosion parameters of 38 stripped-envelope core-collapse supernovae
Joe Lyman, David Bersier, Phil James +4
Literature data are collated for 38 stripped-envelope core-collapse supernovae (SE SNe; i.e. SNe IIb, Ib, Ic and Ic-BL) that have good light curve coverage in more than one optical…
SN2011hs: a Fast and Faint Type IIb Supernova from a Supergiant Progenitor
F. Bufano, G. Pignata, M. Bersten +33
Observations spanning a large wavelength range, from X-ray to radio, of the Type IIb supernova 2011hs are presented, covering its evolution during the first year after explosion. T…
