Evolution, Explosion, and Nucleosynthesis of Core‐Collapse Supernovae
The Astrophysical Journal, 2003 We present a new set of presupernova evolutions and explosive yields of massive stars of initial solar composition (Y=0.285, Z=0.02) in the mass range 13-35 Msun. All the models have been computed with the latest version (4.97) of the FRANEC code that now includes a nuclear network extending from neutrons to Mo98. The explosive nucleosynthesis has been

Chiral transport of neutrinos in supernovae
EPJ Web of Conferences, 2017 The conventional neutrino transport theory for core-collapse supernovae misses one key property of neutrinos: the left-handedness. The chirality of neutrinos modifies the hydrodynamic behavior at the macroscopic scale and leads to topological transport ...

Dust Formation and Destruction in Core Collapse Supernovae Explosions [PDF]
Dust is a crucial component of the Interstellar Medium (ISM) and an important driver in many astrophysical processes. Dust formed from evolved stars increases the metallicity of the ISM, enriching it with heavier elements.

Gravitational Waves due to Population III Core Collapse Supernovae
, 2012 Faculty Advisor: Professor Vuk MandicMy goal was to examine the accuracy of the claim in Sandick et al (2006) that LIGO would be able to observe Gravitational Waves emitted from the core collapse supernovae of Population III stars.This research was ...

The Astrophysical Journal LettersThis study reports detection of rare p -process isotopes within presolar grains. Presolar grains are relic dust grains from dying stars. These microscopic dust particles are found in primitive solar system materials.

A New Mechanism for Gravitational-Wave Emission in Core-Collapse Supernovae [PDF]
, 2006 We present a new theory for the gravitational wave signatures of core-collapse supernovae. Previous studies identified axisymmetric rotating core collapse, core bounce, postbounce convection, and anisotropic neutrino emission as the primary processes and

Nucleosynthesis and Clump Formation in a Core-Collapse Supernova
The Astrophysical Journal, 2000 High-resolution two-dimensional simulations were performed for the first five minutes of the evolution of a core collapse supernova explosion in a 15 solar mass blue supergiant progenitor. The computations start shortly after bounce and include neutrino-matter interactions by using a light-bulb approximation for the neutrinos, and a treatment of the ...

Discovery of a Relativistic Stripped-envelope Type Ic-BL Supernova at z = 2.83 with JWST
The Astrophysical Journal LettersWe present James Webb Space Telescope (JWST) NIRCam and NIRSpec observations of a Type Ic supernova (SN Ic) and its host galaxy (JADES-GS+53.13533-27.81457) at z = 2.83. This SN (named SN 2023adta) was identified in deep JWST/NIRCam imaging from the JWST
