The Singular Behaviour of Ambipolar Diffusion Revealed by 1D Cartesian Solutions
F. Moreno-Insertis, E. R. Priest, D. Nóbrega-Siverio
Aims. We seek to (a) study 1D Cartesian ambipolar diffusion near null points; (b) characterise the nonlinear eigenmodes for ambipolar diffusion; (c) propose tests for ambipolar dif…

Extreme-ultraviolet synthesis of nanojet-like ejections due to coalescing flux ropes
Samrat Sen, A. Ramada C. Sukarmadji, D. Nóbrega-Siverio +3
Detection and characterization of small-scale energetic events such as nanoflares and nanojets remain challenging owing to their short lifetimes, small spatial extent, and relative…

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…
