Research Summary

Shock Triggered Star Formation (Shule Li, Adam Frank, Eric Blackman)
Studying the triggering condition and post-triggering evolution for triggered star formation. Also study the influence of initial cloud rotation and magnetic field.
Simulation Components: shock running over otherwise stable Bonnor-Ebert sphere to trigger collapse.

Multiphysics in AstroBEAR (Shule Li)
Implement multiphysics functionality into AstroBEAR. The first set of physics includes: thermal conduction, viscosity and resistivity.
Simulation Components: operator splitting, explicit and implicit thermal conduction, viscosity and resistivity.

Resistive MHD and NLUF project (Shule Li, Adam Frank)
We test the resistive MHD functionality. We run through tests such as Sweet-Parker box, magnetic island formation. The resistive MHD can be used to simulate the shock clump interaction experiment for the NLUF project.
Simulation Components: SP jet launching, magnetic islands, lab astro, resistive shock-clump interaction

Force-Free Magnetic Field (Shule Li)
Force-Free Magnetic Field can be used to set up the contained magnetic field inside a stable cloud (BE sphere configuration). We implement routines in AstroBEAR to generate force-free magnetic field, which can be contained within a clump.
Simulation Components: eigen functions for force-free magnetic field configuration

Shock Interaction with Magnetized Clumps (Shule Li, Adam Frank, Eric Blackman)
Magnetic field can greatly influence the shock interaction with a clump. While previous simulations have been focusing on the case where the global uniform field scenario, in this project, we study the shock interaction with tangled magnetic field contained inside the clump.
Simulation Components: contained tangled magnetic field (toroidal, poloidal and random field configurations) interaction with incoming shocks.

Thermal Conduction and Ablative RT Problem (Shule Li, Baowei Liu, Adam Frank)
Nonlinear thermal conduction can be proven theoretically to be helpful when used to suppressing the RT instability in the ICF experiments. In this project, we implement implicit nonlinear thermal conduction solver and test it with the ablative RT problem.
Simulation Components: Nonlinear thermal conduction implicit solver, ablative Rayleigh-Taylor instability in ICF.
