    Antolin, Patrick; Dolliou, A.; Auchère, F.; Chitta, L.P.; Parenti, S.; Berghmans, D.; Aznar Cuadrado, R.; Barczynski, K.; Gissot, S.; Harra, L.; Huang, Z.; Janvier, M.; Kraaikamp, E.; Long, D.M.; Mandal, S.; Peter, H.; Rodriguez, L.; Schühle, U.; Smith, P.J.; Solanki, S.K.; Stegen, K.; Teriaca, L.; Verbeeck, C.; West, M.J.; Zhukov, A.N.; Appourchaux, T.; Aulanier, Guillaume; Buchlin, E.; Delmotte, F.; Gilles, J.M.; Haberreiter, M.; Halain, J.-P.; Heerlein, K.; Hochedez, J.-F.; Gyo, M.; Poedts, S.; Rochus, P. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Context. Coronal rain is the most dramatic cooling phenomenon of the solar corona. Recent observations in the visible and UV spectrum have shown that coronal rain is a pervasive phenomenon in active regions. Its strong ...
  • First perihelion of EUI on the Solar Orbiter mission 
    Berghmans, D.; Antolin, Patrick; Auchère, F.; Aznar Cuadrado, R.; Barczynski, K.; Chitta, L.P.; Gissot, S.; Harra, L.; Huang, Z.; Janvier, M.; Kraaikamp, E.; Long, D.M.; Mandal, S.; Mierla, M.; Parenti, S.; Peter, H.; Rodriguez, L.; Schühle, U.; Smith, P.J.; Solanki, S.K.; Stegen, K.; Teriaca, L.; Verbeeck, C.; West, M.J.; Zhukov, A.N.; Appourchaux, T.; Aulanier, Guillaume; Buchlin, E.; Delmotte, F.; Gilles, J.M.; Haberreiter, M.; Halain, J.-P.; Heerlein, K.; Hochedez, J.-F.; Gyo, M.; Poedts, S.; Renotte, E.; Rochus, P. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Context. The Extreme Ultraviolet Imager (EUI) on board Solar Orbiter consists of three telescopes: the two High Resolution Imagers, in EUV (HRI EUV ) and in Lyman- α (HRI Lya ), and the Full Sun Imager (FSI). Solar Orbiter/EUI ...
  • SPICE connection mosaics to link the Sun's surface and the heliosphere 
    Varesano, T.; Hassler, D.M.; Zambrana Prado, N.; Plowman, J.; Del Zanna, G.; Parenti, S.; Mason, H.E.; Giunta, A.; Auchère, F.; Carlsson, Mats; Fludra, A.; Peter, H.; Müller, D.; Williams, D.; Aznar Cuadrado, R.; Barczynski, K.; Buchlin, E.; Caldwell, M.; Fredvik, Terje; Grundy, T.; Guest, S.; Harra, L.; Janvier, M.; Kucera, T.; Leeks, S.; Schmutz, W.; Schuehle, U.; Sidher, S.; Teriaca, L.; Thompson, W.; Yardley, S.L. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)
    Aims. We present an analysis of the first connection mosaic made by the SPICE instrument on board the ESA/NASA Solar Orbiter mission on March 2, 2022. The data will be used to map coronal composition that will be compared ...
  • Ultra-high-resolution observations of persistent null-point reconnection in the solar corona 
    Cheng, X.; Priest, E.R.; Li, H.T.; Chen, J.; Aulanier, Guillaume; Chitta, L.P.; Wang, Y.L.; Peter, H.; Zhu, X.S.; Xing, C.; Ding, M.D.; Solanki, S.K.; Berghmans, D.; Teriaca, L.; Aznar Cuadrado, R.; Zhukov, A.N.; Guo, Y.; Long, D.; Harra, L.; Smith, P.J.; Rodriguez, L.; Verbeeck, C.; Barczynski, K.; Parenti, S. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Abstract 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-resolution extreme ultraviolet ...
