  • Analysis of the Evolution of a Multi-Ribbon Flare and Failed Filament Eruption 
    Joshi, Reetika; Mandrini, Cristina H.; Chandra, Ramesh; Schmieder, Birgitte; Cristiani, Germán D.; Mac Cormack, Cecilia; Démoulin, Pascal; Cremades, Hebe (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Abstract How filaments form and erupt are topics about which solar researchers have wondered for more than a century and they are still open to debate. We present observations of a filament formation, its failed eruption, ...
  • Case study of multi-temperature coronal jets for emerging flux MHD models 
    Joshi, Reetika; Chandra, Ramesh; Schmieder, Brigitte; Moreno-Insertis, Fernando; Aulanier, Guillaume; Nóbrega Siverio, Daniel Elias; Devi, Pooja (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Context. Hot coronal jets are a basic observed feature of the solar atmosphere whose physical origin is still actively debated. Aims. We study six recurrent jets that occurred in active region NOAA 12644 on April 4, 2017. ...
  • Deciphering Solar Coronal Heating: Energizing Small-scale Loops through Surface Convection 
    Nóbrega Siverio, Daniel Elias; Moreno-Insertis, F.; Galsgaard, K.; Krikova, Kilian; Rouppe van der Voort, Luc; Joshi, Reetika; Madjarska, M.S. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Abstract The solar atmosphere is filled with clusters of hot small-scale loops commonly known as coronal bright points (CBPs). These ubiquitous structures stand out in the Sun by their strong X-ray and/or ...
  • Interaction of solar jets with filaments: Triggering of large-amplitude filament oscillations 
    Joshi, Reetika; Luna, Manuel; Schmieder, Birgitte; Moreno-Insertis, Fernando; Chandra, Ramesh (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Context. Large-amplitude oscillations (LAOs) are often detected in filaments. Using multi-wavelength observations, their origin can be traced back to the interaction with eruptions and jets. Aims. We present two different ...
