    The K2-ESPRINT Project. II. Spectroscopic Follow-up of Three Exoplanet Systems from Campaign 1 of K2
    We report on Doppler observations of three transiting planet candidates that were detected during Campaign 1 of the K2 mission. The Doppler observations were...

    The Kennicutt-Schmidt Relation in Extremely Metal-Poor Dwarf Galaxies
    The Kennicutt-Schmidt (KS) relation between the gas mass and star formation rate (SFR) describes the star formation regulation in disk galaxies. It is a...

    The Kepler Follow-up Observation Program. II. Stellar Parameters from Medium- and High-resolution Spectroscopy
    We present results from spectroscopic follow-up observations of stars identified in the Kepler field and carried out by teams of the Kepler Follow-up...

    The Kinematic Status and Mass Content of the Sculptor Dwarf Spheroidal Galaxy
    We present VLT FLAMES spectroscopic observations (R~6500) in the Ca II triplet region for 470 probable kinematic members of the Sculptor (Scl) dwarf spheroidal...

    The Large-Scale Ionized Outflow of CH Cygni
    Hubble Space Telescope (HST) and ground-based [O II] and [N II] images obtained in the period 1996-1999 reveal a complex, ionized optical nebula around the...

    The Lazy Giants: APOGEE Abundances Reveal Low Star Formation Efficiencies in the Magellanic Clouds
    We report the first APOGEE metallicities and α-element abundances measured for 3600 red giant stars spanning a large radial range of both the Large (LMC) and...

    The Line Emission Region in III Zw 2: Kinematics and Variability
    We have studied the Lyα, Hβ, Hα, and Mg II λ2798 line profiles of the Seyfert 1 galaxy III Zw 2. The shapes of these broad emission lines show evidence of a...

    The Line-of-Sight Velocity Distributions of Intracluster Planetary Nebulae in the Virgo Cluster Core
    Radial velocities of 40 intracluster planetary nebulae (ICPNs) in the Virgo Cluster were obtained with the new multifiber FLAMES spectrograph on UT2 at the Very...

    The Lithium Depletion Boundary and the Age of the Hyades Cluster
    Determination of the lithium depletion boundary (LDB), i.e., the observational limit below which the cores of very low-mass objects do not reach high enough...
