Magnetic flux cancellation in the solar atmosphere through 3D realistic numerical modeling
F. Moreno-Insertis, V. H. Hansteen, D. Nóbrega-Siverio
We present a radiation-magnetohydrodynamics (RMHD) simulation of a magnetic cancellation event. The model is calculated with the Bifrost code and spans from the uppermost convectio…
Spectropolarimetric synthesis of forbidden lines in MHD models of coronal bright points
Ernest Alsina Ballester, Daniel Nóbrega-Siverio, Fernando Moreno-Insertis +1
The inference of the magnetic field vector from spectropolarimetric observations is crucial for understanding the physical processes governing the solar corona. We investigate whic…
Merging plasmoids and nanojet-like ejections in a coronal current sheet
Samrat Sen, F. Moreno-Insertis
Forced magnetic reconnection is triggered by external perturbations, which are ubiquitous in the solar corona. This process plays a crucial role in the energy release during solar…
Study of the excitation of large amplitude oscillations in a prominence by nearby flares
Manuel Luna, Reetika Joshi, Brigitte Schmieder +3
Large amplitude oscillations commonly occur in solar prominences, triggered by energetic phenomena such as jets and flares. On March 14-15, 2015, a filament partially erupted in tw…
