Two-dimensional simulations of internal gravity waves in a 5 Zero-Age-Main-Sequence model
A. Le Saux, I. Baraffe, T. Guillet +5
Main-sequence intermediate-mass stars present a radiative envelope that supports internal gravity waves (IGWs). Excited at the boundary with the convective core, IGWs propagate tow…
A study of convective core overshooting as a function of stellar mass based on two-dimensional hydrodynamical simulations
I. Baraffe, J. Clarke, A. Morison +6
We perform two-dimensional numerical simulations of core convection for zero-age-main-sequence stars covering a mass range from 3 to 20 . The simulations are per…
Impact of radial truncation on global 2D hydrodynamic simulations for a Sun-like model
D. G. Vlaykov, I. Baraffe, T. Constantino +5
Stellar convection is a non-local process responsible for the transport of heat and chemical species. It can lead to enhanced mixing through convective overshooting and excitation…
Two-dimensional simulations of solar-like models with artificially enhanced luminosity. II. Impact on internal gravity waves
A. Le Saux, T. Guillet, I. Baraffe +7
Artificially increasing the luminosity and the thermal diffusivity of a model is a common tactic adopted in hydrodynamical simulations of stellar convection. In this work, we analy…
Local heating due to convective overshooting and the solar modelling problem
Baraffe I, Constantino T, Clarke J +5
Recent hydrodynamical simulations of convection in a solar-like model suggest that penetrative convective flows at the boundary of the convective envelope modify the thermal backgr…
Dynamics in a stellar convective layer and at its boundary: Comparison of five 3D hydrodynamics codes
R. Andrassy, J. Higl, H. Mao +18
Our ability to predict the structure and evolution of stars is in part limited by complex, 3D hydrodynamic processes such as convective boundary mixing. Hydrodynamic simulations he…
Two-dimensional simulations of solar-like models with artificially enhanced luminosity -- I. Impact on convective penetration
I. Baraffe, J. Pratt, D. G. Vlaykov +4
We perform 2D, fully compressible, time-implicit simulations of convection in a solar-like model with the MUSIC code. Our main motivation is to explore the impact of a common tacti…
Suppression of lithium depletion in young low-mass stars from fast rotation
Thomas Constantino, Isabelle Baraffe, Thomas Goffrey +4
We compute rotating 1D stellar evolution models that include a modified temperature gradient in convection zones and criterion for convective instability inspired by rotating 3D hy…
