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…

FIP Bias Evolution in an Emerging Active Region as observed in SPICE Synoptic Observations
T. Varesano, D. M. Hassler, N. Zambrana Prado +6
We investigate the time evolution of relative elemental abundances in the context of the first ionization potential effect focusing on an active region. Our aim is to characterize…

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…
