    The First L-Type Brown Dwarf in the Pleiades
    We have obtained low-resolution optical spectra of three faint brown dwarf candidates in the Pleiades open cluster. The objects observed are Roque 12 (I_C=18.5)...

    The First Polarimetric Signatures of Infrared Jets in X-Ray Binaries
    We present near-infrared linear spectropolarimetry of a sample of persistent X-ray binaries, Sco X-1, Cyg X-2, and GRS 1915+105. The slopes of the spectra are...

    The First Precise Determination of an Optical-Far-Ultraviolet Extinction Curve Beyond the Local Group (z=0.83)
    We present the optical-far-ultraviolet extinction curve of the dust in the lens galaxy of the gravitational lens system SBS 0909+532 (z=0.83). Extending our...

    The First Ultracompact Roche Lobe-Filling Hot Subdwarf Binary
    We report the discovery of the first short-period binary in which a hot subdwarf star (sdOB) filled its Roche lobe and started mass transfer to its companion...

    The Forbidden Abundance of Oxygen in the Sun
    We reexamine closely the solar photospheric line at 6300 Å, which is attributed to a forbidden line of neutral oxygen and is widely used in analyses of other...

    The Formation and Disintegration of Magnetic Bright Points Observed by Sunrise/IMaX
    The evolution of the physical parameters of magnetic bright points (MBPs) located in the quiet Sun (mainly in the interwork) during their lifetime is studied...

    The Formation of a 70 M<SUB>☉</SUB> Black Hole at High Metallicity
    A 70 ${M}_{\odot }$ black hole (BH) was discovered in the Milky Way disk in a long-period detached binary system (LB-1) with a high-metallicity 8 ${M}_{\odot }$...

    The Fornax Deep Survey with VST. II. Fornax A: A Two-phase Assembly Caught in the Act
    As part of the Fornax Deep Survey with the ESO VLT Survey Telescope, we present new g- and r-band mosaics of the SW group of the Fornax Cluster. It covers an...

    The Fourth Catalog of Active Galactic Nuclei Detected by the Fermi Large Area Telescope
    The fourth catalog of active galactic nuclei (AGNs) detected by the Fermi Gamma-ray Space Telescope Large Area Telescope (4LAC) between 2008 August 4 and 2016...
