    Non-transiting exoplanets as a means of understanding star–planet interactions in close-in systems
    Previous studies showed evidence of a dearth of close-in exoplanets around fast rotators, which can be explained by the combined action of intense tidal and...

    Nonequilibrium ionization and ambipolar diffusion in solar magnetic flux emergence processes
    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...

    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 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...
