A Fast Numerical Scheme for Causal Relativistic Hydrodynamics with Dissipation
relativistic hydrodynamics relativistic dissipation relativity kinetic theory methods: numerical
2011/9/13
In this paper, we develop a stable and fast numerical scheme for relativistic dissipative hydrodynamics based on Israel-Stewart theory. Israel-Stewart theory is a stable and causal description of diss...
3D numerical MHD modeling of sunspots with radiation transport
MHD – radiative transfer – Sun sunspots – Sun photosphere – Sun magnetic
2010/11/10
Sunspot fine structure has been modeled in the past by a combination of idealized magneto-convection simulations and simplified models that prescribe the magnetic field and flow structure to a large d...
Radiative cooling in numerical astrophysics: the need for adaptive mesh refinement
Computational techniques fluid dynamics Radiative recombination Radiative transfer in astrophysics
2010/11/15
Energy loss through optically thin radiative cooling plays an important part in the evolution of astrophysical gas dynamics and should therefore be considered a necessary element in any numerical simu...
High Energy Cosmic-ray Diffusion in Molecular Clouds: A Numerical Approach
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/22
The propagation of high-energy cosmic rays through giant molecular clouds constitutes a fundamental process in astronomy and astrophysics. The diffusion of cosmic-rays through these magnetically turbu...
