Scientific Background

The unifying theme of this workshop is the computational approach to astrophysical fluids, be they plasmas, neutral clouds, or some mix of the two. Emphasis will be placed on 1) the range of astrophysical applications appropriate to each computational technique, 2) the methodologies developed for including gravity, magnetic fields, radiation transport, dust, energy sinks and sources, and other physical processes, and 3) the algorithmic responses developed to avoid instabilities and unphysical dissipation in the computations. Topics to include:

hydrodynamics and magnetohydrodynamics.

accretion disk instabilities
jet formation
molecular cloud support
origin & growth of cosmic magnetic fields
evolution of galactic magnetic fields
planetary nebulae
astrophysical pair plasmas

multi-phase flows:
- dust and gas in accretion disks & in radiatively-driven winds
turbulence, convection, chaos
evolution of molecular clouds
- interstellar chemistry
- turbulence
star formation
- first generation
- current star formation
- star formation in high-pressure environments
- multiple star and cluster formation
supernovae and novae
- detonations, flame propagation
- nuclear reaction networks
  - thermal pulses
  - r,s, and p processes
computational issues:
- breakdown of the fluid approximation at small scales, low densities
- comparisons of particle versus finite difference methodologies
- advances in adaptive mesh refinement techniques
- test cases for codes
