Critical Conditions for Core-Collapse Supernovae [PDF]

Physical Review Letters, 2012
The explosion of a core-collapse supernova can be approximated by the breakdown of steady-state solutions for accretion onto a proto-neutron star (PNS). We analytically show that as the neutrino luminosity exceeds a critical value L_c, the neutrinosphere pressure exceeds the hydrostatic limit even for an optimal shock radius R.

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

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.

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.

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 ...

Production of Radioactive 22Na in Core-collapse Supernovae: The Ne-E(L) Component in Presolar Grains and Its Possible Consequences on Supernova Observations

The Astrophysical Journal
Presolar graphite grains carry the isotopic signatures of their parent stars. A significant fraction of presolar graphites show isotopic abundance anomalies relative to solar for elements such as O, Si, Mg, and Ca, which are compatible with ...

Exploring Core-Collapse Supernovae through Neutrinos [PDF]

, 2020
Core-collapse supernovae are amongst the brightest objects in the sky. The physical mechanism driving the explosion of these energetic transients is still subject of debate.

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 ...
