Nonlinear Force-Free Magnetic Field Fitting to Coronal Loops with and without Stereoscopy

Markus J. Aschwanden

We developed a new nonlinear force-free magnetic field (NLFFF) forward-fitting algorithm based on an analytical approximation of force-free and divergence-free NLFFF solutions, whi…

A Nonlinear Force-Free Magnetic Field Approximation Suitable for Fast Forward-Fitting to Coronal Loops. III. The Free Energy

Markus J. Aschwanden

An analytical approximation of a nonlinear force-free magnetic field (NLFFF) solution was developed in Paper I, while a numerical code that performs fast forward-fitting of this NL…

The Spatio-Temporal Evolution of Solar Flares Observed with AIA/SDO: Fractal Diffusion, Sub-Diffusion, or Logistic Growth ?

Markus J. Aschwanden

We explore the spatio-temporal evolution of solar flares by fitting a radial expansion model that consists of an exponentially growing acceleration phase, followed by a dece…

First 3D Reconstructions of Coronal Loops with the STEREO A+B Spacecraft: IV. Magnetic Modeling with Twisted Force-Free Fields

Markus J. Aschwanden, Jean-Pierre Wuelser, Nariaki V. Nitta +3

The three-dimensional (3D) coordinates of stereoscopically triangulated loops provide strong constraints for magnetic field models of active regions in the solar corona. Here we us…

Solar Stereoscopy with STEREO/EUVI A and B spacecraft from small (6 deg) to large (170 deg) spacecraft separation angles

Markus J. Aschwanden, Jean-Pierre Wülser, Nariaki Nitta +1

We performed for the first time stereoscopic triangulation of coronal loops in active regions over the entire range of spacecraft separation angles ($α_{sep}\approx 6^\circ, 43^\ci…
