Structure of Convective-Reactive Zone in a Supernova Progenitor
M. Mocak, C. Meakin, F. Rizzuti +5
Convective-reactive events are phases of stellar evolution where turbulent mixing and nuclear burning directly compete, since their timescales become similar within convection zone…
3D simulations of a complete convective silicon shell burning phase
V. Varma, R. Hirschi, F. Rizzuti +7
We present 3D hydrodynamic simulations of a complete silicon shell burning phase until fuel exhaustion at the end of the evolution of a 14 core-collapse supernova progenit…
The Impact of Initial Mass Dependent Convective Boundary Mixing on the Structure and Fates of Massive Stars
Emily E. Whitehead, Raphael Hirschi, Vishnu Varma +4
While convection has been known to play a key role in stars for many decades, its implementation in one-dimensional stellar evolution codes still represents a major uncertainty tod…
Shell mergers in the late stages of massive star evolution: new insight from 3D hydrodynamic simulations
Federico Rizzuti, Raphael Hirschi, Vishnu Varma +6
One-dimensional (1D) stellar evolution models are widely used across various astrophysical fields, however they are still dominated by important uncertainties that deeply affect th…
3D simulations of convective shell Neon-burning in a massive star
C. Georgy, F. Rizzuti, R. Hirschi +6
The treatment of convection remains a major weakness in the modelling of stellar evolution with one-dimensional (1D) codes. The ever increasing computing power makes now possible t…
Convective Properties of Rotating Two-Dimensional Core-Collapse Supernova Progenitors
Emmanouil Chatzopoulos, Sean M. Couch, W. David Arnett +1
We explore the effects of rotation on convective carbon, oxygen, and silicon shell burning during the late stages of evolution in a 20Msun star. Using the Modules for Experiments i…
