The Ubiquity of Twisted Flux Ropes in the Quiet Sun
Tahar Amari, Aurélien Canou, Marco Velli +6
Models and observations have demonstrated that Twisted Flux Ropes (TFRs) play a significant role in the structure and eruptive dynamics of active regions. Their role in the dynamic…

Global Non-Potential Magnetic Models of the Solar Corona During the March 2015 Eclipse
A. R. Yeates, T. Amari, I. Contopoulos +17
Seven different models are applied to the same problem of simulating the Sun's coronal magnetic field during the solar eclipse on 2015 March 20. All of the models are non-potential…

The Influence of Spatial Resolution on Nonlinear Force-Free Modeling
M. L. DeRosa, M. S. Wheatland, K. D. Leka +11
The nonlinear force-free field (NLFFF) model is often used to describe the solar coronal magnetic field, however a series of earlier studies revealed difficulties in the numerical…
