Small-scale impulsive EUV emission enhancements along network loops
A. Dolliou, H. Peter, S. Mandal +4
Network loops are a common feature in the quiet Sun. The physical processes sustaining their energy budget is still under discussion. We rely on a multi-instrumental (Solar Orbiter…

The nature of small scale EUV solar brightenings investigated as impulsive heating of short loops in 1D hydrododynamics simulations
A. Dolliou, J. A. Klimchuk, S. Parenti +1
Small (400 to 4000 km) and short lived (10 to 200 km) extreme ultraviolet (EUV) brightenings, detected by the High Resolution Imager EUV (HRIEUV), have been found to be ubiquitous…

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…
