Convective core entrainment in 1D main sequence stellar models
L. J. A. Scott, R. Hirschi, C. Georgy +5
3D hydrodynamics models of deep stellar convection exhibit turbulent entrainment at the convective-radiative boundary which follows the entrainment law, varying with boundary penet…
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…
AIMS - A new tool for stellar parameter determinations using asteroseismic constraints
B. M. Rendle, G. Buldgen, A. Miglio +12
A key aspect in the determination of stellar properties is the comparison of observational constraints with predictions from stellar models. Asteroseismic Inference on a Massive Sc…
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…
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…
