    K2-399 b is not a planet: The Saturn that wandered through the Neptune desert is actually a hierarchical eclipsing binary
    Context. The transit technique has been very efficient over the past decades in detecting planet-candidate signals. The so-called statistical validation...

    Keck HIRES spectra of the brown dwarf DENIS-P J1228.2-1547
    We report Keck high-resolution echelle spectroscopic observations of two very cool field dwarfs discovered by the near-IR photometric survey DENIS. DENIS-P...

    Keck spectroscopy of z = 1-3 ULIRGs from the Spitzer SWIRE survey
    Context: High-redshift ultra luminous infrared galaxies contribute the bulk of the cosmic IR background and are the best candidates for very massive galaxies in...

    Kepler Object of Interest Network. I. First results combining ground- and space-based observations of Kepler systems with transit timing variations
    During its four years of photometric observations, the Kepler space telescope detected thousands of exoplanets and exoplanet candidates. One of Kepler's...

    Kepler observations of the asteroseismic binary HD 176465
    Binary star systems are important for understanding stellar structure and evolution, and are especially useful when oscillations can be detected and analysed...

    Kepler observations of very low-mass stars
    Observations of very low-mass stars with Kepler represent an excellent opportunity to search for planetary transits and to characterize optical photometric...

    Kepler sheds new and unprecedented light on the variability of a blue supergiant: Gravity waves in the O9.5Iab star HD 188209
    Stellar evolution models are most uncertain for evolved massive stars. Asteroseismology based on high-precision uninterrupted space photometry has become a new...

    Kepler-423b: a half-Jupiter mass planet transiting a very old solar-like star
    We report the spectroscopic confirmation of the Kepler object of interest KOI-183.01 (Kepler-423b), a half-Jupiter mass planet transiting an old solar-like star...
