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 ...

Nuclei in core-collapse supernovae engine

Progress in Particle and Nuclear Physics, 2023
Herein, we review the nuclear equations of state (EOSs) %for core-collapse supernova simulations and the constituent nuclei of core-collapse supernovae (CCSNe) and their roles in CCSN simulations. Various nuclei such as deuterons, iron, and extremely neutron-rich nuclei compose in the central engines of CCSNe.

Equation of State Effects in Core-Collapse Supernovae [PDF]

Physical Review Letters, 2020
We investigate the impact of different properties of the nuclear equation of state in core-collapse supernovae, with a focus on the proto-neutron-star contraction and its impact on the shock evolution. To this end, we introduce a range of equations of state that vary the nucleon effective mass, incompressibility, symmetry energy, and nuclear saturation

The demographics of core-collapse supernovae

Astronomy & Astrophysics
Context. The observational properties of core-collapse supernovae are shaped by the envelopes of their progenitors. In massive binary systems, mass-transfer drastically alters the pre-supernova structures compared to single stars, which leads to a ...

Essential ingredients in core-collapse supernovae

AIP Advances, 2014
Carrying 1044 joules of kinetic energy and a rich mix of newly synthesized atomic nuclei, core-collapse supernovae are the preeminent foundries of the nuclear species which make up our solar system and ourselves.

Binary-stripped stars as core-collapse supernovae progenitors

, 2021
Most massive stars experience binary interactions in their lifetimes that can alter both the surface and core structure of the stripped star with significant effects on their ultimate fate as core-collapse supernovae.

The Progenitor of the S147 Supernova Remnant

The Astrophysical Journal
The supernova remnant (SNR) S147 contains the pulsar PSR J0538+2817 and a likely unbound binary companion, HD 37424. It is the only good Galactic candidate for a binary unbound by a core-collapse supernova.

Synthesis, Characterization, and Anti‐Plasmodium falciparum Activity of a New Copper(II) Complex Containing 2‐(Tert‐Butoxy)‐6‐(1H‐imidazol‐1‐yl)pyridine

ChemMedChem, Volume 21, Issue 11, 15 June 2026.
The graphical abstract illustrates the formation of a Cu(II) complex from azole‐based ligand, highlighting metal–ligand synergy. The resulting coordination compound acts as a bioactive entity against Plasmodium, where metal coordination enhances antiparasitic activity, outperforming the free ligand and demonstrating its potential as an antimalarial ...
