    Novel framework for the three-dimensional NLTE inverse problem
    The inversion of spectropolarimetric observations of the solar upper atmosphere is one of the most challenging goals in solar physics. If we account for all...

    Numerical determination of the cutoff frequency in solar models
    Context. In stratified atmospheres, acoustic waves can only propagate if their frequency is higher than the cutoff value. The determination of the cutoff...

    Numerical modeling of lander interaction with a low-gravity asteroid regolith surface. II. Interpreting the successful landing of Hayabusa2 MASCOT
    Context. The JAXA asteroid sample return mission Hayabusa2 reached its target (162173) Ryugu in June 2018 and released the European (CNES-DLR) lander MASCOT in...

    Numerical simulation of observations with GOLF on board SOHO
    The main objective of the GOLF Experiment (Global Oscillations at Low Frequencies) on-board the SOHO (Solar and Heliospheric Observatory) space mission is the...

    Numerical Simulations of Conversion to Alfvén Waves in Sunspots
    We study the conversion of fast magnetoacoustic waves to Alfvén waves by means of 2.5D numerical simulations in a sunspot-like magnetic configuration. A fast...

    Numerical simulations of exocomet transits: Insights from β Pic and KIC 3542116
    In recent years, the topic of existence and exploration of exocomets has been gaining increasing attention. The asymmetrical decrease in the star's brightness...

    Numerical simulations of large-amplitude oscillations in flux rope solar prominences
    Context. Large-amplitude oscillations (LAOs) of solar prominences are a very spectacular, but poorly understood, phenomena. These motions have amplitudes larger...

    Numerical simulations of linear magnetohydrodynamic waves in two-dimensional force-free magnetic fields
    High resolution observations of the solar corona made with instruments onboard the SOHO and TRACE spacecrafts have provided new evidence for the presence of...

    Numerical simulations of prominence oscillations triggered by external perturbations
    Context. Several energetic disturbances have been identified as triggers of large-amplitude oscillations (LAOs) in prominences. Observations show that Moreton...
