Nucleosynthesis in type II supernovae [PDF]
Nuclear Physics A, 1997 Presupernova evolution and explosive nucleosynthesis in massive stars for main-sequence masses from 13 $M_\odot$ to 70 $M_\odot$ are calculated. We examine the dependence of the supernova yields on the stellar mass, $^{12}C( , ) ^{16}O}$ rate, and explosion energy.

Binary progenitor systems for Type Ic supernovae [PDF]
Nature CommunicationsCore-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 ...

Understanding Type II Supernovae [PDF]
International Astronomical Union Colloquium, 2005 SummaryWe present the results of a systematic analysis of a group of Type II plateau supernovae that span a large range in luminosities, from faint objects like SN 1997D and 1999br to very luminous events like SN 1992am. The physical properties of the supernovae appear to be related to the plateau luminosity or the expansion velocity.

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 ...

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.

The Astrophysical Journal, 2023 Previous numerical simulations of double-peaked Type IIb supernova (SN IIb) light curves have demonstrated that the radius and mass of the hydrogen-rich envelope of the progenitor star can significantly influence the brightness and timescale of the early-
