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…
Dynamics of small-scale convective motions
Birgit Lemmerer, Arnold Hanslmeier, Herbert Muthsam +1
Previous studies have discovered a population of small granules with diameters less than 800 km showing differing physical properties. High resolution simulations and observations…
Multidimensional modelling of classical pulsating stars
Herbert J. Muthsam, Friedrich Kupka
After an overview of general aspects of modelling the pulsation- convection interaction we present reasons why such simulations (in multidimensions) are needed but, at the same tim…
Multidimensional realistic modelling of Cepheid-like variables-II: Analysis of a Cepheid model
Eva Mundprecht, Herbert J. Muthsam, Friedrich Kupka
Non-local, time-dependent convection models have been used to explain the location of double-mode pulsations in Cepheids in the HR diagram as well as the existence and location of…
Achievable Efficiency of Numerical Methods for Simulations of Solar Surface Convection
Hannes Grimm-Strele, Friedrich Kupka, Herbert J. Muthsam
We investigate the achievable efficiency of both the time and the space discretisation methods used in Antares for mixed parabolic-hyperbolic problems. We show that the fifth order…
Curvilinear Grids for WENO Methods in Astrophysical Simulations
Hannes Grimm-Strele, Friedrich Kupka, Herbert J. Muthsam
We investigate the applicability of curvilinear grids in the context of astrophysical simulations and WENO schemes. With the non-smooth mapping functions from Calhoun et al. (2008)…
