This research proposes a multi-scale, multi-physics simulation framework to capture the transition from weak to strong magnetic fields during gravitational collapse in star formation. It combines adaptive mesh refinement, a unified treatment of non-ideal MHD effects, and a chemistry network approximation to enable simulations from molecular cloud scales to protostellar core scales.
Key findings
The framework addresses the magnetic braking catastrophe by modeling the decoupling of magnetic fields from neutrals at high densities.
End-to-end simulations capture magnetic field amplification from microgauss to kilogauss.
The method includes baseline comparisons against ideal MHD and validation against observational constraints.
Limitations & open questions
The research is a proposal and the actual implementation and results are pending.
The framework's effectiveness is yet to be confirmed against a broader range of observational data.
