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…
