Solar -mode damping rates: insight from a 3D hydrodynamical simulation
K. Belkacem, F. Kupka, R. Samadi +1
Space-borne missions CoRoT and Kepler have provided a rich harvest of high-quality photometric data for solar-like pulsators. It is now possible to measure damping rates for hundre…
Structure of the solar photosphere studied from the radiation hydrodynamics code ANTARES
P. Leitner, B. Lemmerer, A. Hanslmeier +4
The ANTARES radiation hydrodynamics code is capable of simulating the solar granulation in detail unequaled by direct observation. We introduce a state-of-the-art numerical tool to…
Two-dimensional segmentation of small convective patterns in radiation hydrodynamics simulations
B. Lemmerer, D. Utz, A. Hanslmeier +4
Recent results from high-resolution solar granulation observations indicate the existence of a population of small granular cells that are smaller than 600 km in diameter. These sm…
Realistic Simulations of Stellar Surface Convection with ANTARES: I. Boundary Conditions and Model Relaxation
H. Grimm-Strele, F. Kupka, B. Löw-Baselli +3
We have implemented open boundary conditions into the ANTARES code to increase the realism of our simulations of stellar surface convection. Even though we greatly benefit from the…
Simulations of stellar convection, pulsation and semiconvection
Herbert J. Muthsam, Friedrich Kupka, Eva Mundprecht +3
We report on modelling in stellar astrophysics with the ANTARES code. First, we describe properties of turbulence in solar granulation as seen in high-resolution calculations. Then…
