Three-dimensional magnetic reconnection in unipolar regions. A case study of coronal bright points in the Sun

D. Nóbrega-Siverio, F. Moreno-Insertis, A. S. H. To

Magnetic reconnection is a fundamental mechanism underlying the heating and a wide variety of eruptive phenomena in the solar atmosphere; however, characterizing its 3D aspects rem…

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…

Small-scale magnetic flux emergence preceding a chain of energetic solar atmospheric events

D. Nóbrega-Siverio, I. Cabello, S. Bose +4

Advancements in instrumentation have revealed a multitude of small-scale EUV events in the solar atmosphere. Our aim is to employ high-resolution magnetograms to gain a detailed un…

A comparative study of resistivity models for simulations of magnetic reconnection in the solar atmosphere. II. Plasmoid formation

Øystein Håvard Færder, Daniel Nóbrega-Siverio, Mats Carlsson

Plasmoid-mediated reconnection plays a fundamental role in different solar atmospheric phenomena. Numerical reproduction of this process is therefore essential for developing robus…
