Angular momentum transport in the convection zone of a 3D MHD simulation of a rapidly rotating core-collapse progenitor
Ryota Shimada, Lucy O. McNeill, Vishnu Varma +3
Rotation and magnetic fields in the cores of evolved massive stars in their final phase are thought to play an important role in the subsequent supernova explosion and the formatio…
Resolution Dependence in Magnetohydrodynamic Simulations of Neutrino-Driven Core-Collapse Supernovae
Vishnu Varma, Bernhard Müller
We investigate the role of resolution and initial magnetic field strength on core-collapse supernovae in simulations of a non-rotating progenitor. Specificall…
3D Synthetic Convective Velocity Fields to Initialise Core-Collapse Supernova Simulations from 1D Progenitors
Vishnu Varma, Bernhard Mueller, Raphael Hirschi
Core-collapse supernovae (CCSNe) are among the most energetic and complex astrophysical phenomena, requiring threedimensional (3D) simulations to capture their intricate explosion…
3D Simulations of Magnetoconvection in a Rapidly Rotating Supernova Progenitor
Vishnu Varma, Bernhard Mueller
We present a first 3D magnetohydrodynamic (MHD) simulation of oxygen, neon and carbon shell burning in a rapidly rotating 16 M_sun core-collapse supernova progenitor. We also run a…
3D stellar evolution: hydrodynamic simulations of a complete burning phase in a massive star
F. Rizzuti, R. Hirschi, W. D. Arnett +5
Our knowledge of stellar evolution is driven by one-dimensional (1D) simulations. 1D models, however, are severely limited by uncertainties on the exact behaviour of many multi-dim…
3D Simulations of Strongly Magnetised Non-Rotating Supernovae: Explosion Dynamics and Remnant Properties
Vishnu Varma, Bernhard Mueller, Fabian R. N. Schneider
We investigate the impact of strong initial magnetic fields in core-collapse supernovae of non-rotating progenitors by simulating the collapse and explosion of a 16.9 Msun star for…
