Bolometric light curves and explosion parameters of 38 stripped-envelope core-collapse supernovae
- J. Lyman, D. Bersier, +4 authors E. Pian
- Physics
- 13 June 2014
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 band. Using… Expand
Ultra-bright Optical Transients are Linked with Type Ic Supernovae
- A. Pastorello, S. Smartt, +56 authors US Naval Observatory - Flagstaff Station
- Physics
- 16 August 2010
Recent searches by unbiased, wide-field surveys have uncovered a group of extremely luminous optical transients. The initial discoveries of SN 2005ap by the Texas Supernova Search and SCP-06F6 in a… Expand
The type IIB supernova 2011DH from a supergiant progenitor
- M. Bersten, O. Benvenuto, +10 authors L. Tomasella
- Physics
- 25 July 2012
A set of hydrodynamical models based on stellar evolutionary progenitors is used to study the nature of SN 2011dh. Our modeling suggests that a large progenitor star-with R {approx} 200 R{sub Sun… Expand
THE YELLOW SUPERGIANT PROGENITOR OF THE TYPE II SUPERNOVA 2011dh IN M51
- J. Maund, M. Fraser, +11 authors S. Valenti
- Physics
- 13 June 2011
We present the detection of the putative progenitor of the Type IIb SN 2011dh in archival pre-explosion Hubble Space Telescope images. Using post-explosion Adaptive Optics imaging with Gemini… Expand
The diversity of Type II supernova versus the similarity in their progenitors
- S. Valenti, D. Howell, +21 authors Davis
- Physics
- 29 March 2016
The authors acknowledge the ASASSN, La Silla Quest, and LOSS surveys for discovering new SNe that made this study possible. This material is based upon work supported by the National Science… Expand
The first month of evolution of the slow-rising Type IIP SN 2013ej in M74
- S. Valenti, D. Sand, +17 authors S. Barbara
- Physics
- 17 September 2013
We present early photometric and spectroscopic observations of SN 2013ej, a bright type IIP supernova in M74. SN 2013ej is one of the closest SNe ever discovered. The available archive images and the… Expand
SN 2009jf: a slow-evolving stripped-envelope core-collapse supernova
- S. Valenti, M. Fraser, +32 authors Inaf Padova
- Physics
- 15 June 2011
We present an extensive set of photometric and spectroscopic data for SN 2009jf, a nearby Type Ib supernova (SN), spanning from similar to 20 d before B-band maximum to 1 yr after maximum. We show ...
Optical and near-infrared observations of SN 2011dh – The first 100 days
- M. Ergon, J. Sollerman, +26 authors M. Turatto
- Physics
- 8 May 2013
We present optical and near-infrared (NIR) photometry and spectroscopy of the Type IIb supernova (SN) 2011dh for the first 100 days. We complement our extensive dataset with SWIFT ultra-violet (UV)… Expand
Topologically Trivial Legendrian Knots
- Y. Eliashberg, M. Fraser
- Mathematics
- 16 January 2008
The paper deals with topologically trivial Legendrian knots in tight and overtwisted contact 3-manifolds. The first part contains a thorough exposition of the proof of the classification of… Expand
Three Hypervelocity White Dwarfs in Gaia DR2: Evidence for Dynamically Driven Double-Degenerate Double-Detonation Type Ia Supernovae
- K. Shen, D. Boubert, +23 authors B. J. Williams
- Physics
- 30 April 2018
Double detonations in double white dwarf (WD) binaries undergoing unstable mass transfer have emerged in recent years as one of the most promising Type Ia supernova (SN Ia) progenitor scenarios. One… Expand
