Investigating white-light flare mechanisms via the Paschen jump using high-resolution continuum observations from the Swedish 1-m Solar Telescope
Sascha Ornig, Luc Rouppe van der Voort, Mats Carlsson +4
The continuum is understood to contain a large portion of the energy emitted by a solar flare. The optical continuum, known as white light (WL), is particularly relevant since it m…
The Influence of Opacity on Inferred MHD Wave Signatures in the Lower Solar Atmosphere
Samuel J. Skirvin, Samuel D. T. Grant, David B. Jess +8
Magnetohydrodynamic wave activity in small-scale magnetic structures, such as solar pores, provides key insights into energy transport in the lower solar atmosphere. This study pre…
Shock-induced magnetic reconnection driving Ellerman bomb emission and a spicule
Mats Ola Sand, Quentin Noraz, Guillaume Aulanier +3
The mechanism that forms dynamic type II spicules has remained elusive for many years. Their dynamical behaviour has long been linked to magnetic reconnection, yet no conclusive ev…
Active chromospheric fibril singularity: Coordinated observations from Solar Orbiter, SST, and IRIS
Reetika Joshi, Luc Rouppe van der Voort, Guillaume Aulanier +6
The fine structures of the solar chromosphere, driven by photospheric motions, play a crucial role in the dynamics of solar magnetic fields. Many have been already identified such…
Small-scale dynamic phenomena associated with interacting fan-spine topologies: quiet-Sun Ellerman bombs, UV brightenings, and chromospheric inverted-Y-shaped jets
Aditi Bhatnagar, Avijeet Prasad, Daniel Nóbrega-Siverio +2
QSEBs are small-scale magnetic reconnection events in lower solar atmosphere. Sometimes, they exhibit transition region counterparts, known as UV brightenings. Magnetic field extra…
Quiet Sun Ellerman bombs as a possible proxy for reconnection-driven spicules
Mats Ola Sand, Luc H. M. Rouppe van der Voort, Jayant Joshi +3
Spicules are elongated, jet-like structures that populate the solar chromosphere and are rooted in the photosphere. In recent years, high-resolution observations and advanced numer…
