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…
Co-existence of longitudinal and transverse oscillations in polar plumes observed with Solar Orbiter/EUI
Upasna Baweja, Vaibhav Pant, S. Krishna Prasad +6
Magnetohydrodynamic (MHD) waves play a key role in heating the solar corona and driving the solar wind. Recent observations have shown the presence of slow magneto-acoustic and Alf…
The SPOCA-suite: a software for extraction and tracking of Active Regions and Coronal Holes on EUV images
Véronique Delouille, Benjamin Mampaey, Cis Verbeeck +1
Precise localisation and characterization of active regions and coronal holes as observed by EUV imagers are crucial for a wide range of solar and helio-physics studies. We describ…
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…
Two-Spacecraft Detection of Short-period Decayless Kink Oscillations of Solar Coronal Loops
Sihui Zhong, Valery M. Nakariakov, Dmitrii Y. Kolotkov +2
Decayless kink oscillations of an ensemble of loops are captured simultaneously by the High Resolution Imager (HRI) of the Extreme Ultraviolet Imager (EUI) and the Atmospheric Imag…
Solar flares in the Solar Orbiter era: Short-exposure EUI/FSI observations of STIX flares
Hannah Collier, Laura A. Hayes, Stefan Purkhart +10
Aims: This paper aims to demonstrate the importance of short-exposure extreme ultraviolet (EUV) observations of solar flares in the study of particle acceleration, heating and ener…
A Point-Spread Function for the Extreme Ultraviolet High-Resolution Imager on board Solar Orbiter
Stefan J. Hofmeister, Emil Kraaikamp, Sergei Shestov +7
We present the point-spread function (PSF) of the Extreme Ultraviolet High-Resolution Imager (HRIEUV) onboard Solar Orbiter, which observes the Sun at 174 Angstrom. This PSF provid…
Extreme-ultraviolet transient brightenings in the quiet-Sun corona : Closest-perihelion observations with Solar Orbiter/EUI
Nancy Narang, Cis Verbeeck, Marilena Mierla +9
The extreme-ultraviolet (EUV) brightenings identified by Solar Orbiter, commonly known as campfires, are the smallest transient brightenings detected to date outside active regions…
What drives decayless kink oscillations in active region coronal loops on the Sun?
Sudip Mandal, Lakshmi P. Chitta, Patrick Antolin +19
We study here the phenomena of decayless kink oscillations in a system of active region (AR) coronal loops. Using high resolution observations from two different instruments, namel…
Slow solar wind sources. High-resolution observations with a quadrature view
Krzysztof Barczynski, Louise Harra, Conrad Schwanitz +16
The origin of the slow solar wind is still an open issue. One possibility that has been suggested is that upflows at the edge of an active region can contribute to the slow solar w…
