Active nests at solar maximum: How nested flux emergence dominated flaring activity and structured the heliosphere

Adam J. Finley, Allan Sacha Brun, Antoine Strugarek +5

Multi-viewpoint observations from near-Earth satellites and ESA's Solar Orbiter enable a global view of the Sun. This continuous coverage is essential for characterising active nes…

Nonthermal line broadening at solar flare footpoints is primarily field-aligned

Andy S. H. To, Alexander J. B. Russell

Magnetic reconnection powers solar and stellar flares, but a full understanding of how the released energy is transported and converted within the solar atmosphere remains elusive.…

Signs of Sulphur fractionation under high magnetic field strength

Dominik Orlovskij, Andy S. H. To, David M. Long

Sulphur, with a first ionisation potential (FIP) of 10.36 eV, lies at the boundary between low- and high-FIP elements, making it particularly sensitive to fractionation processes i…

Chromospheric dynamics and turbulence regulate the solar FIP effect

Andy S. H. To, J. Martin Laming, Jeffrey Reep +1

Elemental abundance variations in the solar corona, commonly characterised by First Ionisation Potential (FIP) bias, provide crucial diagnostics of chromospheric processes. The pon…

Comparing First Ionisation Potential bias diagnostics in the solar atmosphere

Kristena D. Spruksta, David M. Long, Andy S. H. To

Plasma composition in the solar atmosphere differs between the photosphere and corona, producing an observable difference in elemental abundance known as the FIP effect. The FIP ef…

Sulfur fractionation in coronal plumes as observed by Solar Orbiter/SPICE

Slimane Mzerguat, Miho Janvier, Eric Buchlin +4

Coronal plumes are bright, narrow structures rooted in coronal holes that contribute to the solar wind. Their composition, particularly elemental fractionation as a function of fir…
