Selected aspects of the analysis of molecular line observation of edge-on circumbinary disks

Roman Avramenko, Sebastian Wolf, Tobias F. Illenseer +1

Context. Inner cavities, accretion arms and density waves are characteristic structures in the density distribution of circumbinary disks. They are the result of the tidal interact…

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…

Lie symmetry analysis and exact solutions of the one-dimensional heat equation with power law diffusivity

Tobias F. Illenseer

A heat equation with non-constant diffusivity depending as a power law on the spatial variable is analysed using Lie's method to identify classical point symmetries. It is shown th…

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…

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…
