UBVRIz Light Curves of 51 Type II Supernovae
Lluís Galbany, Mario Hamuy, Mark M. Phillips +34
We present a compilation of UBV RIz light curves of 51 type II supernovae discovered during the course of four different surveys during 1986 to 2003: the Cerro Tololo Supernova Sur…
Type II supernova diversity
Joseph P. Anderson
It is now firmly established that at a significant fraction of hydrogen-rich type II supernovae (SNe II) arise from red supergiant progenitors. However, a large diversity of SN pro…
A correlation between SN II metal line strength and host HII region oxygen abundance
Joseph P. Anderson, Claudia P. Gutiérrez, Luc Dessart
Dessart et al., demonstrated that type II supernova (SN II) model spectra present increasing metal line strength with increasing progenitor metallicity. To confront these models wi…
The Rise-Time of Type II Supernovae
Santiago Gonzalez-Gaitan, N. Tominaga, J. Molina +14
We investigate the early-time light-curves of a large sample of 223 type II supernovae (SNe) from the Sloan Digital Sky Survey and the Supernova Legacy Survey. Having a cadence of…
SN 2011A: an low-luminosity interacting transient, with a double plateau and strong sodium absorption
T. de Jaeger, J. P. Anderson, G. Pignata +16
We present optical photometry and spectroscopy of the optical transient SN 2011A. Our data spans 140 days after discovery including photometry and 11 epochs of opt…
Statistical studies of supernova environments
Joseph P. Anderson, Phil A. James, Stacey M. Habergham +2
Investigations of the environments of SNe allow statistical constraints to be made on progenitor properties. We review progress that has been made in this field. Pixel statistics u…
A comparative study of Type II-P and II-L supernova rise times as exemplified by the case of LSQ13cuw
E. E. E. Gall, J. Polshaw, R. Kotak +17
We report on our findings based on the analysis of observations of the Type II-L supernova LSQ13cuw within the framework of currently accepted physical predictions of core-collapse…
