The impact of nuclear equations of state on the dynamics and multi-messenger emission of magnetorotational stellar explosions

Astronomy & Astrophysics
Context. The gravitational collapse of massive stars at the end of their lives leads to powerful supernova explosions that produce new stellar-sized compact objects, regulate the dynamics of their host galaxies, and produce new heavy elements that ...

Constraining the Circumstellar Medium Structure and Progenitor Mass-loss History of Interacting Supernovae Through 3D Hydrodynamic Modeling: The Case of SN 2014C

The Astrophysical Journal
We investigate SN 2014C using three-dimensional (3D) hydrodynamic modeling, focusing on its early interaction with a dense circumstellar medium (CSM). Our objective is to uncover the pre-supernova (SN) CSM structure and constrain the progenitor star’s ...

Supernovae Drive Large-scale, Incompressible Turbulence through Small-scale Instabilities

The Astrophysical Journal Letters
The sources of turbulence in our Galaxy may be diverse, but core-collapse supernovae (SNe) alone provide enough energy to sustain a steady-state galactic turbulence cascade at the observed velocity dispersion.

Local 2D Simulations of the Ignition of a Helium Shell Detonation on a White Dwarf by an Impacting Stream

The Astrophysical Journal
The double detonation model is one of the prevalent explosion mechanisms of Type Ia supernovae (SNe Ia) wherein an outer helium shell detonation triggers a core detonation in the white dwarf (WD).

Supernova Hunters Discovery of 24 Optical Transients with Pan-STARRS

, 2020
Here we report the discovery of 24 transient objects as part of the Pan-STARRS Survey for Transients (PSST) found by citizen scientists involved in the Supernova Hunters Zooniverse Project.

How high energy fluxes may affect Rayleigh–Taylor instability growth in young supernova remnants

, 2018
Energy-transport effects can alter the structure that develops as a supernova evolves into a supernova remnant. The Rayleigh–Taylor instability is thought to produce structure at the interface between the stellar ejecta and the circumstellar matter ...

Dynamical Evolution and Radiative Processes of Supernova Remnants [PDF]

, 2016
I outline the dynamical evolution of the shell remnants of supernovae (SNRs), from initial interaction of supernova ejecta with circumstellar material (CSM) through to the final dissolution of the remnant into the interstellar medium (ISM). Supernova ejecta drive a blast wave through any CSM from the progenitor system; as material is swept up, a ...
