The impact of fallback on the compact remnants and chemical yields of core-collapse supernovae [PDF]

, 2020
Fallback in core-collapse supernovae plays a crucial role in determining the properties of the compact remnants and of the ejecta composition. We perform three-dimensional simulations of mixing and fallback for selected non-rotating supernova models to ...

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.

Spectropolarimetry of Supernovae

, 2008
Overwhelming evidence has accumulated in recent years that supernova explosions are intrinsically 3-dimensional phenomena with significant departures from spherical symmetry.

Non-spherical core collapse supernovae and nucleosynthesis [PDF]

, 2000
Motivated by observations of supernova SN 1987A, various authors have simulated Rayleigh-Taylor (RT) instabilities in the envelopes of core collapse supernovae (for a review, see Mueller 1998).

SN 2020bio: A Double-peaked, H-poor Type IIb Supernova with Evidence of Circumstellar Interaction

The Astrophysical Journal, 2023
We present photometric and spectroscopic observations of SN 2020bio, a double-peaked Type IIb supernova (SN) discovered within a day of explosion, primarily obtained by Las Cumbres Observatory and Swift.

Core-collapse supernovae missed by optical surveys [PDF]

, 2012
We estimate the fraction of core-collapse supernovae (CCSNe) that remain undetected by optical SN searches due to obscuration by large amounts of dust in their host galaxies.

Exciting prospects for detecting late-time neutrinos from core-collapse supernovae [PDF]

Physical Review D, 2020
In this theoretical study of successful core-collapse supernovae, the authors provide a detailed model of neutrino emission from the different phases of the transition - explosion to proto-neutron star cooling to late-time formation of either neutron ...

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.

A New Monte Carlo Method for Time-Dependent Neutrino Radiation Transport [PDF]

, 2012
Monte Carlo approaches to radiation transport have several attractive properties compared to deterministic methods. These include simplicity of implementation, high accuracy, and good parallel scaling.
