Multi-wavelength observations of substructures in solar flare ribbons
Vishal Singh, Eamon Scullion, Gert J. J. Botha +6
Solar flare ribbons are extensive brightenings in the chromosphere during flares, often showing fine scale structuring that reflects the underlying energy release. Using high caden…
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…
Fine-scale downflows above flare ribbons captured by Solar Orbiter/EUI
Zheng Sun, Alexander G. M. Pietrow, Malcolm K. Druett +8
In solar flares, flare ribbons map chromospheric footpoints where flare energy deposition occurs. These locations are associated with field aligned energy transport from the corona…
Understanding Solar Flares and Energetic Events: Open questions, observational requirements, and instrumental needs over the coming decade
Malcolm K. Druett, Graham S. Kerr, Joel C. Allred +15
Solar flares are the largest energy-release events in the Solar System, allowing us to study fundamental physical phenomena under extreme conditions. Those include magnetic reconne…
Solar Flux Atlases: The new HARPS-N Quiet Sun Benchmark and Ca II H & K Lines Continuum Normalisation
F. Hanassi-Savari, A. G. M. Pietrow, M. K. Druett +2
Context. Solar flux atlases observe the spatially integrated light from the Sun, treating it as a star. They are fundamental tools for gaining insight into the composition of the S…
