    The frequency distribution of PG 1657+416, a rapidly pulsating sdB star
    We analyse the frequencies shown by the recently discovered pulsating sdB star PG 1657+416. It has at least four frequencies in the range 6.8--7.8 mHz, which...

    The Frequency of Appearance of Bright Naked Eye Comets Since 1750
    It is a typical lament of the astronomers of today that there has been a dearth of bright comets in the 20th century and, particularly in its latter half. Many...

    The frequency of gaseous debris discs around white dwarfs
    A total of 1-3 per cent of white dwarfs are orbited by planetary dusty debris detectable as infrared emission in excess above the white dwarf flux. In a rare...

    The frequency of transiting planetary systems around polluted white dwarfs
    This paper investigates the frequency of transiting planetary systems around metal-polluted white dwarfs using high-cadence photometry from ULTRACAM and...

    The Frontier between Small-scale Bipoles and Ephemeral Regions in the Solar Photosphere: Emergence and Decay of an Intermediate-scale Bipole Observed with SUNRISE/IMaX
    We report on the photospheric evolution of an intermediate-scale (≈4 Mm footpoint separation) magnetic bipole, from emergence to decay, observed in the quiet...

    The Fundamental Metallicity Relation Emerges from the Local Anti-correlation between Star Formation Rate and Gas-phase Metallicity that Exists in Disk Galaxies
    The fundamental metallicity relation (FMR) states that galaxies of the same stellar mass but larger star formation rate (SFR) tend to have smaller gas-phase...

    The fundamental parameters of the Algol binary AI Draconis revisited
    We present the results of an analysis of our infrared light curves of the Algol-type binary AI Draconis in the J, H and K bands, and of published light curves...

    The Fundamental Plane for early-type galaxies: dependence on the magnitude range
    Studying three samples of early-type galaxies, which include approximately 8800 galaxies and cover a relatively ample magnitude range ( ~ 5.5mag), we find that...

    The fundamental plane of dwarf irregular galaxies
    Aims: Near-IR photometry of dwarf irregular galaxies (dIs) has been acquired to expand the sample of objects suitable for investigating the fundamental plane...
