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…
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…
3D Simulations and MLT: I. Renzini's Critique
W. David Arnett, Casey Meakin, Raphael Hirschi +5
Renzini (1987) wrote an influential critique of mixing-length theory (MLT) as used in stellar evolution codes, and concluded that three-dimensional (3D) fluid dynamical simulations…
Turbulent convection in stellar interiors. III. Mean-field analysis and stratification effects
Maxime Viallet, Casey Meakin, David Arnett +1
We present 3D implicit large eddy simulations (ILES) of the turbulent convection in the envelope of a 5 Msun red giant star and in the oxygen-burning shell of a 23 Msun supernova p…
A new stellar mixing process operating below shell convection zones following off-center ignition
M. Mocák, Casey A. Meakin, E. Müller +1
During most stages of stellar evolution the nuclear burning of lighter to heavier elements results in a radial composition profile which is stabilizing against buoyant acceleration…
Multidimensional hydrodynamic simulations of the hydrogen injection flash
Miroslav Mocak, Lionel Siess, Ewald Muller
The injection of hydrogen into the convection shell powered by helium burning during the core helium flash is commonly encountered during the evolution of metal-free and extremely…
Hydrodynamic simulations of shell convection in stellar cores
Miroslav Mocak, Ewald Muller, Lionel Siess
Shell convection driven by nuclear burning in a stellar core is a common hydrodynamic event in the evolution of many types of stars. We encounter and simulate this convection (i) i…
Rayleigh-Taylor finger instability mixing in hydrodynamic shell convection models
Miroslav Mocak, Ewald Mueller
Mixing processes in stars driven by composition gradients as a result of the Rayleigh-Taylor instability are not anticipated. They are supported only by hydrodynamic studies of ste…
The core helium flash revisited III. From Pop I to Pop III stars
Miroslav Mocak, Simon W. Campbell, Ewald Mueller +1
Degenerate ignition of helium in low-mass stars at the end of the red giant branch phase leads to dynamic convection in their helium cores. One-dimensional (1D) stellar modeling of…
The core helium flash revisited: II. Two and three-dimensional hydrodynamic simulations
M. Mocak, E. Mueller, A. Weiss +1
We study turbulent convection during the core helium flash close to its peak by comparing the results of two and three-dimensional hydrodynamic simulations. We use a multidimension…
