Coronal voids and their magnetic nature

J. D. Nölke, S. K. Solanki, J. Hirzberger +68

Extreme ultraviolet (EUV) observations of the quiet solar atmosphere reveal extended regions of weak emission compared to the ambient quiescent corona. The magnetic nature of these…

Evolution of dynamic fibrils from the cooler chromosphere to the hotter corona

Sudip Mandal, Hardi Peter, Lakshmi Pradeep Chitta +17

Dynamic fibrils (DFs) are commonly observed chromospheric features in solar active regions. Recent observations from the Extreme Ultraviolet Imager (EUI) aboard the Solar Orbiter h…

Picoflare jets power the solar wind emerging from a coronal hole on the Sun

L. P. Chitta, A. N. Zhukov, D. Berghmans +17

Coronal holes are areas on the Sun with open magnetic field lines. They are a source region of the solar wind, but how the wind emerges from coronal holes is not known. We observed…

Polarisation of decayless kink oscillations of solar coronal loops

Sihui Zhong, Valery M. Nakariakov, Dmitrii Y. Kolotkov +4

Decayless kink oscillations of plasma loops in the solar corona may contain an answer to the enigmatic problem of solar and stellar coronal heating. The polarisation of the oscilla…

Beyond small-scale transients: a closer look at the diffuse quiet solar corona

J. Gorman, L. P. Chitta, H. Peter +9

Within the quiet Sun corona imaged at 1 MK, much of the field of view consists of diffuse emission that appears to lack the spatial structuring that is so evident in coronal loops…

Fleeting Small-scale Surface Magnetic Fields Build the Quiet-Sun Corona

L. P. Chitta, S. K. Solanki, J. C. del Toro Iniesta +19

Arch-like loop structures filled with million Kelvin hot plasma form the building blocks of the quiet-Sun corona. Both high-resolution observations and magnetoconvection simulation…

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…

Ultra-high-resolution Observations of Persistent Null-point Reconnection in the Solar Corona

X. Cheng, E. R. Priest, H. T. Li +21

Magnetic reconnection is a key mechanism involved in solar eruptions and is also a prime possibility to heat the low corona to millions of degrees. Here, we present ultra-high-reso…

Evidence of external reconnection between an erupting mini-filament and ambient loops observed by Solar Orbiter/EUI

Z. F. Li, X. Cheng, M. D. Ding +16

Mini-filament eruptions are one of the most common small-scale transients in the solar atmosphere. However, their eruption mechanisms are still not understood thoroughly. Here, wit…

Imaging and spectroscopic observations of extreme-ultraviolet brightenings using EUI and SPICE on board Solar Orbiter

Ziwen Huang, L. Teriaca, R. Aznar Cuadrado +16

The smallest extreme-ultraviolet (EUV) brightening events that were detected so far, called campfires, have recently been uncovered by the High Resolution EUV telescope (HRIEUV), w…

Diffuse solar coronal features and their spicular footpoints

Nikolina Milanović, Lakshmi Pradeep Chitta, Hardi Peter

In addition to a component of the emission that originates from clearly distinguishable coronal loops, the solar corona also exhibits extreme-ultraviolet (EUV) and X-ray ambient em…

First Perihelion of EUI on the Solar Orbiter mission

D. Berghmans, P. Antolin, F. Auchère +34

Context. The Extreme Ultraviolet Imager (EUI), onboard Solar Orbiter consists of three telescopes: the two High Resolution Imagers in EUV (HRIEUV) and in Lyman-α (HRILya), and the…

Multi-stage reconnection powering a solar coronal jet

David M. Long, Lakshmi Pradeep Chitta, Deborah Baker +5

Coronal jets are short-lived eruptive features commonly observed in polar coronal holes and are thought to play a key role in the transfer of mass and energy into the solar corona.…
