    The Extreme CNO-enhanced Composition of the Primitive Iron-poor Dwarf Star J0815+4729
    We present an analysis of high-resolution Keck/HIRES spectroscopic observations of J0815+4729, an extremely carbon-enhanced, iron-poor dwarf star. These high...

    The Fast X-Ray Transient XRT 210423 and Its Host Galaxy
    Fast X-ray Transients (FXTs) are X-ray flares with durations ranging from a few hundred seconds to a few hours. Possible origins include the tidal disruption of...

    The Fermi–GBM Three-year X-Ray Burst Catalog
    The Fermi Gamma-ray Burst Monitor (GBM) is an all-sky gamma-ray monitor well known in the gamma-ray burst (GRB) community. Although GBM excels in detecting the...

    The First Extrasolar Planet Discovered with a New-Generation High-Throughput Doppler Instrument
    We report the detection of the first extrasolar planet, ET-1 (HD 102195b), using the Exoplanet Tracker (ET), a new-generation Doppler instrument. The planet...

    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...
