  • Publication
    Short-term spectroscopic monitoring of two cool dwarfs with strong magnetic fields
    Context: There is now growing evidence that some brown dwarfs (BDs) have very strong magnetic fields, and yet their surface temperatures are so low that the...

    Signature of oscillations in coronal bright points
    A detailed study of two consecutive bright points observed simultaneously with the Coronal Diagnostic Spectrometer (CDS), the Extreme ultraviolet Imaging...

    Signatures of Incomplete Paschen-Back Splitting in the Polarization Profiles of the He I λ10830 Multiplet
    We investigate the formation of polarization profiles induced by a magnetic field in the He I multiplet at 10830 Å. Our analysis considers the Zeeman splitting...

    Signatures of Magnetic Reconnection at the Footpoints of Fan-shaped Jets on a Light Bridge Driven by Photospheric Convective Motions
    Dynamical jets are generally found on light bridges (LBs), which are key to studying sunspot decay. So far, their formation mechanism is not fully understood...
  • Publication
    Signatures of the impact of flare-ejected plasma on the photosphere of a sunspot light bridge
    Aims: We investigate the properties of a sunspot light bridge, focusing on the changes produced by the impact of a plasma blob ejected from a C-class flare...
  • Publication
    Simulated interaction of magnetohydrodynamic shock waves with a complex network-like region
    We provide estimates of the wave energy reaching the solar chromosphere and corona in a network-like magnetic field topology, including a coronal null point...
  • Publication
    Simulation of a flux emergence event and comparison with observations by Hinode
    Aims: We study the observational signature of flux emergence in the photosphere using synthetic data from a 3D MHD simulation of the emergence of a twisted flux...

    Simulation of Quiet-Sun Waves in the Ca II Infrared Triplet
    The Ca II infrared triplet lines around 8540 Å are good candidates for observing chromospheric magnetism. Model spectra of these lines are obtained by combining...

    Simulations of magneto-hydrodynamic waves in atmospheres of roAp stars
    We report 2D time-dependent non-linear magneto-hydrodynamical simulations of waves in the atmospheres of roAp stars. We explore a grid of simulations in a wide...
