Relative Importance of Convective Uncertainties in Massive Stars
Etienne A. Kaiser, Raphael Hirschi, W. David Arnett +3
In this work, we investigate the impact of uncertainties due to convective boundary mixing (CBM), commonly called `overshoot', namely the boundary location and the amount of mixing…
Relative Importance of Convective Uncertainties
Etienne A. Kaiser, Raphael Hirschi, W. David Arnett +3
Convection plays a key role in the evolution of stars due to energy transport and mixing of composition. Despite its importance, this process is still not well understood. One long…
3D Simulations and MLT: II. Onsager's Ideal Turbulence
W. David Arnett, Raphael Hirschi, Simon W. Campbell +7
We simulate stellar convection at high Reynolds number (Re7000) with causal time stepping but no explicit viscosity. We use the 3D Euler equations with shock capturing (C…
Progenitors of Core-Collapse Supernovae
Raphael Hirschi, David Arnett, Andrea Cristini +3
Massive stars have a strong impact on their surroundings, in particular when they produce a core-collapse supernova at the end of their evolution. In these proceedings, we review t…
The First 3D Simulations of Carbon Burning in a Massive Star
Andrea Cristini, Casey Meakin, Raphael Hirschi +3
We present the first detailed three-dimensional hydrodynamic implicit large eddy simulations of turbulent convection for carbon burning. The simulations start with an initial radia…
3D Hydrodynamic Simulations of Carbon Burning in Massive Stars
Andrea Cristini, Casey Meakin, Raphael Hirschi +3
We present the first detailed three-dimensional (3D) hydrodynamic implicit large eddy simulations of turbulent convection of carbon burning in massive stars. Simulations begin with…
