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…
Picoflares in the Quiet Solar Corona: Solar Orbiter Observations Halfway to the Sun
O. Podladchikova, A. Warmuth, L. Harra +33
X-ray observations of the Sun led Eugene Parker to propose nanoflares as the basic energy-release units that heat the solar corona. Decades later, Solar Orbiter's Extreme Ultraviol…
Spatial distributions of EUV brightenings in the quiet-Sun
C. J. Nelson, L. A. Hayes, D. Müller +16
The identification of large numbers of localised transient EUV brightenings, with small spatial scales, in the quiet-Sun corona has been one of the key early results from Solar Orb…
First Solar Orbiter observation of a dark halo in the solar atmosphere
Serena Maria Lezzi, David M. Long, Vincenzo Andretta +5
Solar active regions (ARs) are often surrounded by dark large areas of reduced emission compared to the quiet Sun, observed at various wavelengths corresponding to chromosphere, tr…
Searching for evidence of subchromospheric magnetic reconnection on the Sun
D. Baker, L. van Driel-Gesztelyi, A. W. James +13
Within the coronae of stars, abundances of those elements with low first ionization potential (FIP) often differ from their photospheric values. The coronae of the Sun and solar-ty…
