Hydrodynamics of core-collapse supernovae and their progenitors

B Müller - Living Reviews in Computational Astrophysics, 2020 - Springer
Multi-dimensional fluid flow plays a paramount role in the explosions of massive stars as
core-collapse supernovae. In recent years, three-dimensional (3D) simulations of these …

Physical, numerical, and computational challenges of modeling neutrino transport in core-collapse supernovae

A Mezzacappa, E Endeve, OEB Messer… - Living Reviews in …, 2020 - Springer
The proposal that core collapse supernovae are neutrino driven is still the subject of active
investigation more than 50 years after the seminal paper by Colgate and White. The modern …

A new moment-based general-relativistic neutrino-radiation transport code: Methods and first applications to neutron star mergers

D Radice, S Bernuzzi, A Perego… - Monthly Notices of the …, 2022 - academic.oup.com
We present a new moment-based energy-integrated neutrino transport code for neutron star
merger simulations in general relativity. In the merger context, ours is the first code to include …

We present a systematic numerical relativity study of the dynamical ejecta, winds, and
nucleosynthesis in neutron star (NS) merger remnants. Binaries with the chirp mass …

Black Hole Formation Accompanied by the Supernova Explosion of a 40 M⊙ Progenitor Star

A Burrows, D Vartanyan, T Wang - The Astrophysical Journal, 2023 - iopscience.iop.org
We have simulated the collapse and evolution of the core of a solar-metallicity 40 M⊙ star
and find that it explodes vigorously by the neutrino mechanism, despite its very high" …

Exploring fundamentally three-dimensional phenomena in high-fidelity simulations of core-collapse supernovae

EP O'Connor, SM Couch - The Astrophysical Journal, 2018 - iopscience.iop.org
The details of the physical mechanism that drives core-collapse supernovae (CCSNe)
remain uncertain. While there is an emerging consensus on the qualitative outcome of …

Where, when, and why: Occurrence of fast-pairwise collective neutrino oscillation in three-dimensional core-collapse supernova models

H Nagakura, A Burrows, L Johns, GM Fuller - Physical Review D, 2021 - APS
Fast-pairwise collective neutrino oscillation represents a key uncertainty in the theory of core-
collapse supernova (CCSN). Despite the potentially significant impact on CCSN dynamics, it …

Characterizing the gravitational wave signal from core-collapse supernovae

D Radice, V Morozova, A Burrows… - The Astrophysical …, 2019 - iopscience.iop.org
We study the gravitational wave (GW) signal from eight new 3D core-collapse supernova
simulations. We show that the signal is dominated by f-and g-mode oscillations of the …
