Simple Waves in Ideal Radiation Hydrodynamics
Bryan M. Johnson
In the dynamic diffusion limit of radiation hydrodynamics, advection dominates diffusion; the latter primarily affects small scales and has negligible impact on the large scale flo…

Orbital Advection by Interpolation: A Fast and Accurate Numerical Scheme for Super-Fast MHD Flows
Bryan M. Johnson, Xiaoyue Guan, Charles F. Gammie
In numerical models of thin astrophysical disks that use an Eulerian scheme, gas orbits supersonically through a fixed grid. As a result the time step is sharply limited by the Cou…
