The Computational Stellar Astrophysics (CSA) group uses numerical models to study:
Models used by the CSA group:
- Coronal structure and dynamics, as well as coronal heating of other stars.
- Plasma physics in exoplanetary systems - this research involves interplanetary physics and space weather of close-in exoplanets, star-planet magnetic interaction, and magnetospheric dynamics and physics of the upper atmospheres of close-in planets.
- The corona and interplanetary environment of the young Sun.
- Radiation and ionization in accretion disks.
- Novae Hydrodynamics.
- BATS-R-US - global Magnetohydrodynamic (MHD) code (U. of Michigan).
- PINTofALE - Package for Interactive Analysis of Line Emission.
- MOCASSIN - MOnte CArlo SimulationS of Ionized Nebulae.
- FLASH - global model for Hydrodynamic and MHD (U. of Chicago).
