    Search for an extended VHE γ-ray emission from Mrk 421 and Mrk 501 with the MAGIC Telescope
    Context. Part of the very high energy γ-ray radiation coming from extragalactic sources is absorbed through the pair production process on the extragalactic...

    Search for flares and associated CMEs on late-type main-sequence stars in optical SDSS spectra
    Aims: This work aims to detect and classify stellar flares and potential stellar coronal mass ejection (CME) signatures in optical spectra provided by the Sloan...

    Search for forced oscillations in binaries. III. Improved elements and the detection of line-profile variability of the B4V + A6V: system AR Cassiopeiae
    An analysis of a new and extensive set of spectroscopic observations of the early-type binary system {AR Cas} , based also on spectral disentangling, has led to...

    Search for free-floating planetary-mass objects in the Pleiades
    Aims: We aim at identifying the least massive population of the solar metallicity, young (120 Myr), nearby (133.5 pc) Pleiades star cluster with the ultimate...

    Search for Galactic runaway stars using Gaia Data Release 1 and HIPPARCOS proper motions
    Context. The first Gaia Data Release (DR1) significantly improved the previously available proper motions for the majority of the Tycho-2 stars. Aims: We wish...

    Search for nearby stars among proper motion stars selected by optical-to-infrared photometry. II. Two late M dwarfs within 10 pc
    We have identified two late M dwarfs within 10 pc of the Sun, by cross-correlating the Luyten NLTT catalogue of stars with proper motions larger than 0.18...

    Search for photospheric footpoints of quiet Sun transition region loops
    Context: The footpoints of quiet Sun Transition Region (TR) loops do not seem to coincide with the photospheric magnetic structures appearing in traditional low...

    Search for planets around stars with wide brown dwarfs
    Aims: This work aims to better understand the role of wide brown dwarf companions in planetary systems. Methods: We obtained high-resolution spectra of six...
