Comparison of two- and three-dimensional compressible convection in a pre-main sequence star
J. Pratt, I. Baraffe, T. Goffrey +4
Extending our recent studies of two-dimensional stellar convection to 3D, we compare three-dimensional hydrodynamic simulations to identically set-up two-dimensional simulations, f…
A well-balanced scheme for the simulation tool-kit A-MaZe: implementation, tests, and first applications to stellar structure
M. V. Popov, R. Walder, D. Folini +6
Characterizing stellar convection in multiple dimensions is a topic at the forefront of stellar astrophysics. Numerical simulations are an essential tool for this task. We present…
Benchmarking the Multi-dimensional Stellar Implicit Code MUSIC
T. Goffrey, J. Pratt, M. Viallet +6
We present the results of a numerical benchmark study for the MUlti-dimensional Stellar Implicit Code (MUSIC) based on widely applicable two- and three-dimensional compressible hyd…
Spherical-shell boundaries for two-dimensional compressible convection in a star
J. Pratt, I. Baraffe, T. Goffrey +6
Context: We study the impact of two-dimensional spherical shells on compressible convection. Realistic profiles for density and temperature from a one-dimensional stellar evolution…
Multi-dimensional structure of accreting young stars
