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…
Initial radiometric calibration of the High-Resolution EUV Imager () of the Extreme Ultraviolet Imager (EUI) instrument onboard Solar Orbiter
S. Gissot, F. Auchère, D. Berghmans +21
The telescope was calibrated on ground at the Physikalisch-Technische Bundesanstalt (PTB), Germany's national metrology institute, using the Metrology L…
A multiple spacecraft detection of the 2 April 2022 M-class flare and filament eruption during the first close Solar Orbiter perihelion
M. Janvier, S. Mzerguat, P. R. Young +56
The Solar Orbiter mission completed its first remote-sensing observation windows in the spring of 2022. On 2/4/2022, an M-class flare followed by a filament eruption was seen both…
EUV brightenings in the quiet-Sun: Signatures in spectral and imaging data from the Interface Region Imaging Spectrograph
C. J. Nelson, F. Auchère, R. Aznar Cuadrado +13
Localised transient EUV brightenings, sometimes named `campfires', occur throughout the quiet-Sun. However, there are still many open questions about such events, in particular reg…
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…
Multimass modelling of Milky Way globular clusters -- I. Implications on their stellar initial mass function above 1 M
Nolan Dickson, Vincent Hénault-Brunet, Holger Baumgardt +2
The distribution of stars and stellar remnants (white dwarfs, neutron stars, black holes) within globular clusters holds clues about their formation and long-term evolution, with i…
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…
