The rise-time of Type II supernovae [PDF]

Monthly Notices of the Royal Astronomical Society, 2015
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 a few days and sufficient non-detections prior to explosion, we constrain rise-times, i.e.

Analysis of blueshifted emission peaks in Type II supernovae [PDF]

Monthly Notices of the Royal Astronomical Society, 2014
In classical P-Cygni profiles, theory predicts emission to peak at zero rest velocity. However, supernova spectra exhibit emission that is generally blue shifted. While this characteristic has been reported in many supernovae, it is rarely discussed in any detail.

Binary progenitor systems for Type Ic supernovae [PDF]

Nature Communications
Core-collapse supernovae are explosions of massive stars at the end of their evolution. They are responsible for metal production and for halting star formation, having a significant impact on galaxy evolution.

The Iron Yield of Core-collapse Supernovae

The Astrophysical Journal, 2023
We present a systematic analysis of 191 stripped-envelope supernovae (SE SNe), aimed at computing their ^56 Ni masses from the luminosity in their radioactive tails ( ${M}_{\mathrm{Ni}}^{\mathrm{tail}}$ ) and/or in their maximum light, and the mean ^56 ...

HYDRODYNAMICAL MODELS OF TYPE II PLATEAU SUPERNOVAE [PDF]

The Astrophysical Journal, 2011
We present bolometric light curves of Type II-plateau supernovae (SNe II-P) obtained using a newly developed, one-dimensional Lagrangian hydrodynamic code with flux-limited radiation diffusion. Using our code we calculate the bolometric light curve and photospheric velocities of SN1999em obtaining a remarkably good agreement with observations despite ...

Possible Detection of the Progenitor of the Type II Supernova SN 2023ixf

The Astrophysical Journal Letters, 2023
Stellar evolution theory predicts multiple pathways to the explosive deaths of stars as supernovae. Locating and characterizing the progenitors of well-studied supernovae is important to constrain the theory and to justify and design future surveys to ...
