    Galactic Populations of Radio and Gamma-Ray Pulsars in the Polar Cap Model
    We simulate the characteristics of the Galactic population of radio and γ-ray pulsars using Monte Carlo techniques. At birth, neutron stars are spatially...

    Generation of galactic disc warps due to intergalactic accretion flows onto the disc
    A new method is developed to calculate the amplitude of the galactic warps generated by a torque due to external forces. This takes into account that the warp...

    GONG Catalog of Solar Filament Oscillations Near Solar Maximum
    We have cataloged 196 filament oscillations from the Global Oscillation Network Group Hα network data during several months near the maximum of solar cycle 24...

    Granulation and magnetism in the solar atmosphere.
    The properties of the photosphere in magnetic and non magnetic regions, at two levels in the solar atmosphere, have been studied, using two virtually...

    Heat transfer in sunspot penumbrae. Origin of dark-cored penumbral filaments
    Context: Observations at 0.1 arcsec have revealed the existence of dark cores in the bright filaments of sunspot penumbrae. Expectations are high that such dark...

    Heating of the Partially Ionized Solar Chromosphere by Waves in Magnetic Structures
    In this paper, we show a “proof of concept” of the heating mechanism of the solar chromosphere due to wave dissipation caused by the effects of partial...

    Height Dependence of the Penumbral Fine-scale Structure in the Inner Solar Atmosphere
    We studied the physical parameters of the penumbra in a large and fully developed sunspot, one of the largest over the last two solar cycles, by using full...

    Height Variation of the Vector Magnetic Field in Solar Spicules
    Proving the magnetic configuration of solar spicules has hitherto been difficult due to the lack of spatial resolution and image stability during off-limb...

    Heights of formation for measurements of atmospheric parameters.
    We argue that heights of formation (HOFs) should not be assigned to spectral lines since a single line my sample very different layers of the atmosphere...
