    Full Stokes observations in the He i 1083 nm spectral region covering an M3.2 flare
    We present an exceptional data set acquired with the Vacuum Tower Telescope (Tenerife, Spain) covering the pre-flare, flare, and post-flare stages of an M3.2...

    Further evidence for the presence of a neutron star in 4U 2206+54. INTEGRAL and VLA observations
    The majority of High Mass X-ray Binaries (HMXBs) behave like X-ray pulsars, revealing that they contain a magnetised neutron star. Among the four HMXBs showing...

    G-Band Spectral Synthesis in Solar Magnetic Concentrations
    Narrowband imaging in the G band is commonly used to trace the small magnetic field concentrations of the Sun, although the mechanism that makes them bright has...

    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...

    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...
