    MHD waves with mixed properties/Alfvén waves with pressure variations: a review
    Non-uniformity plays an important role for MHD waves. For a uniform plasma of infinite extent the MHD waves can be subdivided in two classes with distinct...

    MISMA inversion of HINODE SOT/SP data. Preliminary results
    We analyze full Stokes observations of a quiet Sun region at disk center taken with the spectropolarimeter of the Solar Optical Telescope aboard the HINODE...

    Mixed properties of MHD waves in non-uniform plasmas
    This paper investigates the mixed properties of MHD waves in a non-uniform plasma. It starts with a short revision of MHD waves in a uniform plasma of infinite...

    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...

    Morphology and Dynamics of Solar Prominences from 3D MHD Simulations
    In this paper we present a numerical study of the time evolution of solar prominences embedded in sheared magnetic arcades. The prominence is represented by a...

    Moving Magnetic Features as Prolongation of Penumbral Filaments
    A sequence of 633 high spatial resolution magnetograms and continuum images from SOHO MDI of NOAA AR 0330 is used to study moving magnetic feature (MMF)...

    Multi-layer Study of Wave Propagation in Sunspots
    We analyze the propagation of waves in sunspots from the photosphere to the chromosphere using time series of co-spatial Ca II H intensity spectra (including...
