    Signal detection for spectroscopy and polarimetry
    The analysis of high spectral resolution spectroscopic and spectropolarimetric observations constitutes a very powerful way of inferring the dynamical...

    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 the Galactic bar in high-order moments of proper motions measured by Gaia
    Our location in the Milky Way provides an exceptional opportunity to gain insight on the galactic evolution processes, and complement the information inferred...

    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...

    Silicon in the dayside atmospheres of two ultra-hot Jupiters
    Atmospheres of highly irradiated gas giant planets host a large variety of atomic and ionic species. Here we observe the thermal emission spectra of the two...

    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...

    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 resonance scattering helioseismometer signals from spatially resolved images: Application to the GOLF instrument on SOHO
    A step in the analysis of the data from the GOLF (Global Oscillations at Low Frequency) instrument on SOHO (SOlar and Heliospheric Observatory, an ESA/NASA...

    Simulations of the Biermann battery mechanism in two-fluid partially ionised plasmas
    Context. In the absence of an initial seed, the Biermann battery term of a non-ideal induction equation acts as a source that generates weak magnetic fields...
