    Joint action of Hall and ambipolar effects in 3D magneto-convection simulations of the quiet Sun. I. Dissipation and generation of waves
    The partial ionization of the solar plasma causes several nonideal effects such as the ambipolar diffusion, the Hall effect, and the Biermann battery effect...

    Joint LIGO and TAMA300 search for gravitational waves from inspiralling neutron star binaries
    We search for coincident gravitational wave signals from inspiralling neutron star binaries using LIGO and TAMA300 data taken during early 2003. Using a simple...

    Large-amplitude Longitudinal Oscillations Triggered by the Merging of Two Solar Filaments: Observations and Magnetic Field Analysis
    We follow the eruption of two related intermediate filaments observed in Hα (from GONG) and EUV (from Solar Dynamics Observatory SDO/Atmospheric Imaging...

    Line Asymmetries and the Microstructure of Photospheric Magnetic Fields
    A systematic structuring of magnetic fields over scales much smaller than the mean free path of photospheric photons may be responsible for the observed...

    Line Formation Theory for the Multiterm Atom with Hyperfine Structure in a Magnetic Field
    Within the framework of the quantum theory of polarized line formation, in the limit of complete frequency redistribution and of the collisionless regime, we...

    Long-term evolution of three light bridges developed on the same sunspot
    One important feature of sunspots is the presence of light bridges. These structures are elongated and bright (as compared to the umbra) features that seem to...

    Low-lying magnetic loops in the solar internetwork
    Aims:We study the structure of the magnetic field vector in the internetwork and search for the presence of small-scale loops. Methods: We invert 1.56 μm...

    Magnetic activity in the photosphere of CoRoT-Exo-2a. Active longitudes and short-term spot cycle in a young Sun-like star
    Context: The space experiment CoRoT has recently detected transits by a hot Jupiter across the disc of an active G7V star (CoRoT-Exo-2a) that can be considered...
