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…
Science Requirement Document (SRD) for the European Solar Telescope (EST) (3rd Edition, December 2025)
Rolf Schlichenmaier, Luis R. Bellot Rubio, Manuel Collados Vera +31
The European Strategy Forum on Research Infrastructures (ESFRI) included the European Solar Telescope (EST) as an ESFRI Project in its 2016 Roadmap and confirmed this status in 202…
Time-dependent Stellar Flare Models of Deep Atmospheric Heating
Adam F. Kowalski, Joel C. Allred, Mats Carlsson
Optical flares have been observed from magnetically active stars for many decades; unsurprisingly, the spectra and temporal evolution are complicated. For example, the shortcomings…
EMISSA: Exploring millimetre indicators of solar-stellar activity III. Comparison of Ca II indices and millimetre continua in a 3D model atmosphere
Sneha Pandit, Sven Wedemeyer, Mats Carlsson
The Ca II H & K lines are strong chromospheric diagnostics that can be used to determine the temperature stratification and magnetic structure of the solar atmosphere. The Atacama…
