Magnetic Field Modeling with Stereoscopy and Magnetograms
Abstract
We developed a new code to reconstruct the 3D magnetic field of solar active regions using stereoscopically triangulated loops with STEREO/A+B and magnetogram data from MDI or HMI. We are using potential field models as well as non-potential field models (nonlinear quasi-force-free fields) that can be quickly forward-fitted to observations using parameterizations of analytical approximations of uniformly twisted flux tubes. This method improves the misalignment angles between theoretical models and observed magnetic fields down to 5 degrees.
