    Magnetospheric accretion onto the T Tauri star AA Tauri. I. Constraints from multisite spectrophotometric monitoring
    We have monitored the photometric, spectroscopic and polarimetric variations of the classical T Tauri star (CTTS) AA Tau over a period of a month. The light...

    Modeling the second solar spectrum . An empirical approach
    We present an empirical approach to model the wing polarization of strong resonance lines. This procedure based on `last scattering approximation' (LSA) was...

    Modelling the radio pulses of an ultracool dwarf
    Context. Recently, unanticipated magnetic activity in ultracool dwarfs (UCDs, spectral classes later than M7) has emerged from a number of radio observations...
