  • Ambipolar diffusion in the Bifrost code 
    Nóbrega Siverio, Daniel Elias; Martinez-Sykora, Juan; Moreno-Insertis, Fernando; Carlsson, Mats (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Context. Ambipolar diffusion is a physical mechanism related to the drift between charged and neutral particles in a partially ionized plasma that is key to many different astrophysical systems. However, understanding its ...
  • 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. ...
  • 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 ...
  • Nonequilibrium ionization and ambipolar diffusion in solar magnetic flux emergence processes 
    Nóbrega Siverio, Daniel Elias; Moreno-Insertis, Fernando; Martinez-Sykora, Juan; Carlsson, Mats; Szydlarski, Mikolaj Marcin (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Context. Magnetic flux emergence from the solar interior has been shown to be a key mechanism for unleashing a wide variety of phenomena. However, there are still open questions concerning the rise of the magnetized plasma ...
  • The chromospheric component of coronal bright points. Coronal and chromospheric responses to magnetic-flux emergence 
    Madjarska, Maria S.; Chae, Jongchul; Moreno-Insertis, Fernando; Hou, Zhenyong; Nóbrega Siverio, Daniel Elias; Kwak, Hannah; Galsgaard, Klaus; Cho, Kyuhyoun (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Context. We investigate the chromospheric counterpart of small-scale coronal loops constituting a coronal bright point (CBP) and its response to a photospheric magnetic-flux increase accompanied by co-temporal CBP heating. ...
