    Solar multiobject multiframe blind deconvolution with a spatially variant convolution neural emulator
    Context. The study of astronomical phenomena through ground-based observations is always challenged by the distorting effects of Earth's atmosphere. Traditional...

    Solar polarimetry in the K I D2 line : A novel possibility for a stratospheric balloon
    Of the two solar lines, K I D1 and D2, almost all attention so far has been devoted to the D1 line, as D2 is severely affected by an O2 atmospheric band. This...

    Solar polarimetry through the K I lines at 770 nm
    We characterize the K I D1 & D2 lines in order to determine whether they could complement the 850 nm window, containing the Ca II infrared triplet lines and...

    Spectral characterisation of 14 V-type candidate asteroids from the MOVIS catalogue
    Most of the currently known basaltic (V-type) asteroids are believed to be past or present members of the Vesta dynamical family. The rising discoveries of V...
