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…
Multidimensional low-Mach number time-implicit hydrodynamic simulations of convective helium shell burning in a massive star
L. Horst, R. Hirschi, P. V. F. Edelmann +2
Context. Multidimensional hydrodynamic simulations of convection in stellar interiors are numerically challenging, especially for flows at low Mach numbers. Methods. We explore the…
Well-balanced treatment of gravity in astrophysical fluid dynamics simulations at low Mach numbers
P. V. F. Edelmann, L. Horst, J. P. Berberich +5
Accurate simulations of flows in stellar interiors are crucial to improving our understanding of stellar structure and evolution. Because the typically slow flows are merely tiny p…
Photometric detection of internal gravity waves in upper main-sequence stars. II. Combined TESS photometry and high-resolution spectroscopy
D. M. Bowman, S. Burssens, S. Simón-Díaz +5
Context. Massive stars are predicted to excite internal gravity waves (IGWs) by turbulent core convection and from turbulent pressure fluctuations in their near-surface layers. The…
Fully compressible simulations of waves and core convection in main-sequence stars
L. Horst, P. V. F. Edelmann, R. Andrassy +4
Context. Recent, nonlinear simulations of wave generation and propagation in full-star models have been carried out in the anelastic approximation using spectral methods. Although…
