Evidence for plasmoid formation related to a hot UV burst in the solar atmosphere
Mats Ola Sand, Luc Rouppe van der Voort, Souvik Bose +4
Magnetic reconnection in the solar atmosphere drives energetic phenomena such as Ellerman bombs, UV bursts, and surges. We used coordinated observations from the Swedish 1-m Solar…
On the Origin of Coronal Picoflare Jets
Annu Bura, Daniel Nóbrega-Siverio, Tanmoy Samanta +1
Small-scale jet-like eruptions, such as picoflare jets and jetlets, are recognized as potential contributors to coronal heating and solar wind acceleration, yet their physical orig…
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…
Structures and properties of fan-shaped jets: H dark blobs and transparent regions
Heesu Yang, Maria S. Madjarska, EunKyung Lim +2
We investigated three fan-shaped jets observed above sunspot light bridges or nearby sunspot regions. The study aimed to explore the dynamics and physical properties of jets' featu…
Synthesizing Sun-as-a-star flare spectra from high-resolution solar observations
M. De Wilde, A. G. M. Pietrow, M. K. Druett +22
Spatially resolved observations of the Sun and the astronomical sample size of stellar bodies are the respective key strengths of solar and stellar observations. However, the large…
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…
Thin coronal jets and plasmoid-mediated reconnection: Insights from Solar Orbiter observations and Bifrost simulations
D. Nóbrega-Siverio, R. Joshi, E. Sola-Viladesau +2
Coronal jets are ubiquitous, collimated million-degree ejections that contribute to the energy and mass supply of the upper solar atmosphere and the solar wind. Solar Orbiter provi…
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…
Magnetic Topology of quiet-Sun Ellerman bombs and associated Ultraviolet brightenings
Aditi Bhatnagar, Avijeet Prasad, Luc Rouppe van der Voort +2
Quiet-Sun Ellerman bombs (QSEBs) are small-scale magnetic reconnection events in the lower atmosphere of the quiet Sun. Recent work has shown that a small percentage of them can oc…
High-resolution observational analysis of flare ribbon fine structures
Jonas Thoen Faber, Reetika Joshi, Luc Rouppe van der Voort +4
Context. Since the mechanism of energy release from solar flares is still not fully understood, the study of fine-scale features developing during flares becomes important for prog…
High-resolution observations of recurrent jets from an arch filament system
Reetika Joshi, Luc Rouppe van der Voort, Brigitte Schmieder +4
Solar jets are collimated plasma ejections along magnetic field lines observed in hot (EUV jets) and cool (chromospheric surges) temperature diagnostics. Their trigger mechanisms a…
Extreme-ultraviolet (EUV) observables of simulated plasmoid-mediated reconnection in the solar corona
Ø. H. Færder, D. Nóbrega-Siverio, M. Carlsson +1
Understanding the role of magnetic reconnection in the heating and dynamics of the solar atmosphere requires detailed observational data of any observable aspect of the reconnectio…
Generic low-atmosphere signatures of swirled-anemone jets
Reetika Joshi, Guillaume Aulanier, Alice Radcliffe +4
Solar jets are collimated plasma flows moving along magnetic field lines and accelerated at low altitude following magnetic reconnection. Several of them originate from anemone-sha…
Evidence of multithermal nature of spicular downflows. Impact on solar atmospheric heating
Souvik Bose, Luc Rouppe van der Voort, Jayant Joshi +4
Spectroscopic observations of the emission lines formed in the solar transition region (TR) commonly show persistent downflows of the order of 10--15 km/s. The cause of such downfl…
A case-study of multi-temperature coronal jets for emerging flux MHD models
Reetika Joshi, Ramesh Chandra, Brigitte Schmieder +4
Context: Hot coronal jets are a basic observed feature of the solar atmosphere whose physical origin is still being actively debated. Aims: We study six recurrent jets occurring in…
