    (1) Stellar kinematics in double-barred galaxies: the sigma-hollows (2) A colorful view on the outskirt of spiral galaxies: clues on disk-formation scenarios
    (1) We present SAURON integral-field stellar velocity and velocity dispersion maps for four double-barred early-type galaxies: NGC2859, NGC3941,NGC4725 and...

    (1) The effect of magnetic fields on solar abundance determinations (2) The solar photosphere in 3D. This time from observations
    (1) In a recently published differential analysis (see Fabbian et al) we have derived abundance corrections for iron lines, using synthetic spectra from solar...

    A Be-type star with a black hole companion
    Stellar-mass black holes have all been discovered through X-ray emission, which arises from the accretion of gas from their binary companions. Currently known...

    A black hole in Swift J1357.2-0933 obscured by an inner disc torus
    X-ray transients are binary systems composed by a 'normal' star which is transfering mass onto a compact object (either a black hole or a neutron star) through...

    A giant planet candidate transiting a white dwarf
    The formation and evolution of planets in general is closely linked to the life of their host star. What happens to the planetary systems at the end stages of...

    Accretion and outflows in black-hole binaries: The extreme case of V404 Cyg
    X-ray observations performed during the last few decades have provided a rich data base on accreting black holes and neutron stars in X-ray binaries. A strong...

    An ionised bubble before the epoch of re-ionisation
    Re-ionisation followed the dark ages when enough stars and galaxies had been formed that their ionising output was sufficient for the task. Population III stars...

    Are chromospheric fibrils tracing the magnetic field?
    Fibrils are thin elongated features visible in the solar chromosphere in and around magnetized regions. Because of their visual appearance they have been...
