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…

Long-lived coronal loops in solar active regions

N. Vasantharaju, H. Peter, L. P. Chitta +1

Coronal loops are plasma structures in the solar atmosphere with temperatures reaching millions of Kelvin, shaped and sustained by the magnetic field. However, their morphology and…

Stereoscopic observations reveal coherent morphology and evolution of solar coronal loops

B. Ram, L. P. Chitta, S. Mandal +2

Coronal loops generally trace magnetic lines of force in the upper solar atmosphere. Understanding the loop morphology and its temporal evolution has implications for coronal heati…

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…

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…

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…

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…

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…

Solar coronal heating from small-scale magnetic braids

L. P. Chitta, H. Peter, S. Parenti +19

Relaxation of braided coronal magnetic fields through reconnection is thought to be a source of energy to heat plasma in active region coronal loops. However, observations of activ…
