    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...

    Multi-parametric Study of Rising 3D Buoyant Flux Tubes in an Adiabatic Stratification Using AMR
    We study the buoyant rise of magnetic flux tubes embedded in an adiabatic stratification using two-and three-dimensional, magnetohydrodynamic simulations. We...

    Multi-Scale Analysis of Magnetic Fields in Filamentary Molecular Clouds
    Using polarimetry, at both visible and submillimeter wavelengths, we propose to study the role and to compare the structure of the magnetic fields within and...

    Multi-scale Analysis of Magnetic Fields in Filamentary Molecular Clouds in Orion A
    New visible and K-band polarization measurements of stars surrounding molecular clouds in Orion A and stars in the Becklin-Neugebauer (BN) vicinity are...
