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…
Formation and rising phase of a flux rope through data-constrained simulations
M. V. Sieyra, A. Strugarek, A. Prasad +8
Context. Data-constrained models incorporate observed photospheric magnetic fields. However, due to the lack of magnetic field information in the rest of the solar atmosphere, mode…
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…
Emergence of magnetic flux sheets in the quiet Sun. I. Statistical properties
S. M. Díaz-Castillo, C. E. Fischer, F. Moreno-Insertis +3
Small-scale magnetic flux emergence in the quiet Sun is crucial for maintaining solar magnetic activity. On the smallest scales studied so far, namely within individual granules, t…
