    Flare in the Galactic stellar outer disc detected in SDSS-SEGUE data
    Aims: We explore the outer Galactic disc up to a Galactocentric distance of ≈30 kpc to derive its parameters and measure the magnitude of its flare. Methods: We...

    FliPer: A global measure of power density to estimate surface gravities of main-sequence solar-like stars and red giants
    Asteroseismology provides global stellar parameters such as masses, radii, or surface gravities using mean global seismic parameters and effective temperature...

    FliPerClass: In search of solar-like pulsators among TESS targets
    The NASA Transiting Exoplanet Survey Satellite (TESS) is about to provide full-frame images of almost the entire sky. The amount of stellar data to be analysed...

    Fluorescence of [Fe II] in H II regions
    A study of [Fe Ii] lines at various positions within the H Ii regions M42 and M43 is presented. The relative intensities of selected optical [Fe Ii] lines are...

    Fluorine abundances in dwarf stars of the solar neighbourhood
    Context. In spite of many observational efforts to characterize the chemical evolution of our Galaxy, not much is known about the origin of fluorine (F). Models...

    FOCUS: a deconvolution method based on algorithmic complexity
    A new method for improving the resolution of images is presented. It is based on Occam's razor principle implemented using algorithmic complexity arguments. The...

    Follow-up observations of binary ultra-cool dwarfs
    Context: Astrometric observations of resolved binaries provide estimates of orbital periods and will eventually lead to measurement of dynamical masses. Only a...

    Follow-up observations of extremely metal-poor stars identified from SDSS
    Context. The most metal-poor stars in the Milky Way witnessed the early phases of formation of the Galaxy, and have chemical compositions that are close to the...
