A radiation hydrodynamics scheme on adaptive meshes using the Variable Eddington Tensor (VET) closure
Shyam H. Menon, Christoph Federrath, Mark R. Krumholz +3
We present a new algorithm to solve the equations of radiation hydrodynamics (RHD) in a frequency-integrated, two-moment formulation. Novel features of the algorithm include i) the…
VETTAM: A scheme for radiation hydrodynamics with adaptive mesh refinement using the variable Eddington tensor method
Shyam H. Menon, Christoph Federrath, Mark R. Krumholz +3
We present Variable Eddington Tensor-closed Transport on Adaptive Meshes (\texttt{VETTAM}), a new algorithm to solve the equations of radiation hydrodynamics (RHD) with support for…
Closing the gap to convergence of gravitoturbulence in local simulations
Jannes Klee, Tobias F. Illenseer, Manuel Jung +1
Aims. Our goal is to find a converged cooling limit for fragmentation in self-gravitating disks. This is especially interesting for the formation of planets, brown dwarfs or stars…
Multi-scale simulations of black hole accretion in barred galaxies: Self-gravitating disk models
Manuel Jung, Tobias F. Illenseer, Wolfgang J. Duschl
Due to the non-axisymmetric potential of the central bar, barred spiral galaxies form, in addition to their characteristic arms and bar, a variety of structures within the thin gas…
Multi-scale simulations of black hole accretion in barred galaxies: Numerical methods and tests
Manuel Jung, Tobias F. Illenseer, Wolfgang J. Duschl
Due to the non-axisymmetric potential of the central bar, barred spiral galaxies form, in addition to their characteristic arms and bar, a variety of structures within the thin gas…
The impact of numerical oversteepening on the fragmentation boundary in self-gravitating disks
Jannes Klee, Tobias F. Illenseer, Manuel Jung +1
Context. It is still an open issue whether a self-gravitating accretion disk fragments. There are many different physical and numerical explanations for fragmentation, but simulati…
Resolving vortices with an isothermal HLLC Riemann solver
Manuel Jung, Tobias F. Illenseer, Wolfgang J. Duschl
The importance of contact discontinuities in 2D isothermal flows has rarely been discussed, since most Riemann solvers are derived for 1D Euler equations. We present a new contact…
