Fast and periodic propagating disturbances along coronal loops detected with EUI on board Solar Orbiter

A. Dolliou, S. Mandal, K. Barczynski +9

Recent high-resolution observations from the Solar Orbiter mission can help detect the indirect signatures of heating at the smallest scales. In this work we measure the properties…

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…

Spectroscopic evidence of cool plasma in quiet Sun HRIEUV small scale brightenings

A. Dolliou, S. Parenti, K. Bocchialini

Context: A large number of the small and the short-lived EUV brightenings have been detected in the quiet Sun (QS) over the past three years, by the High Resolution Imager of the E…

EUV fine structure and variability associated with coronal rain revealed by Solar Orbiter/EUI HRIEUV and SPICE

P. Antolin, A. Dolliou, F. Auchère +34

Coronal rain is the most dramatic cooling phenomenon of the solar corona and an essential diagnostic tool for the coronal heating properties. A puzzling feature of the solar corona…

Temperature of Solar Orbiter/EUI quiet Sun small scale brightenings: evidence for a cooler component

A. Dolliou, S. Parenti, F. Auchère +16

Context: On 2020 May 30, small and short-lived EUV brightenings were observed in the Quiet Sun (QS) during a four minutes sequence by EUI/HRIEUV on board Solar Orbiter. Their physi…
