Optical photometry and spectroscopy of the low-luminosity, broad-lined Ic supernova iPTF15dld
E. Pian, L. Tomasella, E. Cappellaro +37
Core-collapse stripped-envelope supernova (SN) explosions reflect the diversity of physical parameters and evolutionary paths of their massive star progenitors. We have observed th…
Radiation-hydrodynamical modelling of underluminous type II plateau Supernovae
M. L. Pumo, L. Zampieri, S. Spiro +5
With the aim of improving our knowledge about the nature of the progenitors of low-luminosity Type II plateau supernovae (LL SNe IIP), we made radiation-hydrodynamical models of th…
Supernova rates from the SUDARE VST-Omegacam search II. Rates in a galaxy sample
M. T. Botticella, E. Cappellaro, L. Greggio +24
This is the second paper of a series in which we present measurements of the Supernova (SN) rates from the SUDARE survey. In this paper, we study the trend of the SN rates with the…
The possible detection of a binary companion to a Type Ibn supernova progenitor
J. R. Maund, A. Pastorello, S. Mattila +2
We present late-time observations of the site of the Type Ibn supernova (SN) 2006jc acquired with the Hubble Space Telescope Advanced Camera for Surveys. A faint blue source is rec…
Revisiting the Lick Observatory Supernova Search Volume-Limited Sample: Updated Classifications and Revised Stripped-Envelope Supernova Fractions
Isaac Shivvers, Maryam Modjaz, Weikang Zheng +11
We re-examine the classifications of supernovae (SNe) presented in the Lick Observatory Supernova Search (LOSS) volume-limited sample with a focus on the stripped-envelope SNe. The…
Type Ibn Supernovae Show Photometric Homogeneity and Spectral Diversity at Maximum Light
Griffin Hosseinzadeh, Iair Arcavi, Stefano Valenti +34
Type Ibn supernovae (SNe) are a small yet intriguing class of explosions whose spectra are characterized by low-velocity helium emission lines with little to no evidence for hydrog…
