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…
Inspectorch: Efficient rare event exploration in solar observations
C. J. DÃaz Baso, I. J. Soler Poquet, C. Kuckein +2
The Sun is observed in unprecedented detail, enabling studies of its activity on very small spatiotemporal scales. However, the large volume of data collected by our telescopes can…
Accelerating 3D Non-LTE Synthesis with Graph Neural Networks
A. Vicente Arévalo, A. Asensio Ramos, C. J. DÃaz Baso
Spectropolarimetric interpretation of chromospheric lines requires solving the radiative transfer problem under non-local thermodynamic equilibrium (non-LTE) conditions. This means…
IRIS NUV diagnostics for Ellerman bombs: spectral properties, thermodynamics, and formation height
I. J. Soler Poquet, C. J. DÃaz Baso, A. Sainz Dalda +3
Context. Ellerman bombs (EBs) are observational signatures of small-scale magnetic reconnection, key to understanding the lower solar atmosphere. While their role in active regions…
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…
Thermodynamic and magnetic evolution of an eruptive C-class solar flare observed with SST/TRIPPEL-SP
C. J. DÃaz Baso, J. de la Cruz RodrÃguez, H. -P. Doerr +4
Solar flares are complex phenomena driven by the release of magnetic energy, but a large energy reservoir is not sufficient to determine their eruptive potential; the magnetic topo…
