Core-Collapse Supernova neutrino detection with KM3NeT [PDF]

EPJ Web of Conferences, 2019
Core Collapse Supernovae (CCSNe) are explosive phenomena that may occur at the end of the life of massive stars, releasing over 99% of the energy through neutrino emission.

The Three Dimensional Evolution to Core Collapse of a Massive Star [PDF]

, 2015
We present the first three dimensional (3D) simulation of the final minutes of iron core growth in a massive star, up to and including the point of core gravitational instability and collapse.

On core collapse

The Astrophysical Journal, 1991
Stars clusters undergo core collapse on a thermal time scale. This results follows from a detailed simulations in the form of N-body, Fokker-Planck, and gas sphere models. The shrinking of the core, both in size as well as mass, is often heuristically attributed to the negative heat capacity of gravity, as follows from the virial theorem. However, this

Hydrodynamic Mixing of Accretion Disk Outflows in Collapsars: Implications for r-process Signatures

The Astrophysical Journal, 2023
The astrophysical environments capable of triggering heavy-element synthesis via rapid neutron capture (the r -process) remain uncertain. While binary neutron star mergers (NSMs) are known to forge r -process elements, certain rare supernovae (SNe) have ...

RES-NOVA sensitivity to core-collapse and failed core-collapse supernova neutrinos

Journal of Cosmology and Astroparticle Physics, 2021
RES-NOVA is a new proposed experiment for the investigation of astrophysical neutrino sources with archaeological Pb-based cryogenic detectors. RES-NOVA will exploit Coherent Elastic neutrino-Nucleus Scattering (CE$ $NS) as detection channel, thus it will be equally sensitive to all neutrino flavors produced by Supernovae (SNe).

Multiwavelength View of Circumstellar Interaction in Supernovae

Universe
The interaction of post-explosion supernova ejecta with the surrounding circumstellar medium creates emissions across the electromagnetic spectrum. Since the circumstellar medium is created by the mass lost from the progenitor star, it carries tell-tale ...

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 consequences of nuclear electron capture in core collapse supernovae

, 2003
The most important weak nuclear interaction to the dynamics of stellar core collapse is electron capture, primarily on nuclei with masses larger than 60. In prior simulations of core collapse, electron capture on these nuclei has been treated in a highly

Bulk neutrinos and core collapse supernovae [PDF]

, 2002
We discuss the phenomenology of neutrino mixing with bulk fermions in the context of supernova physics. The constraints on the parameter space following from the usual energy loss argument can be relaxed by four orders of magnitude due to a feedback ...
