    The Metallicity Distribution Functions of SEGUE G and K Dwarfs: Constraints for Disk Chemical Evolution and Formation
    We present the metallicity distribution function (MDF) for 24,270 G and 16,847 K dwarfs at distances from 0.2 to 2.3 kpc from the Galactic plane, based on...

    The Metallicity Distribution of Intracluster Stars in Virgo
    We have used the Hubble Space Telescope's Advanced Camera for Surveys (ACS) to detect and measure ~5300 stars in a single intracluster field in the Virgo...

    The metallicity distributions in high-latitudes with SDSS
    We present metallicities and their variations with different parameters for 36 high-latitude fields covering Galactic longitudes 0° l ⩽ 360°. The metallicities...

    The metallicity gradient of M 33: chemical abundances of H ii regions
    Context: We present spectroscopic observations of a sample of 72 emission-line objects, including mainly H ii regions, in the spiral galaxy M 33. Spectra were...

    The metallicity of Palomar 1
    Palomar 1 is a peculiar Galactic globular cluster suspected of being younger than the bulk of Galactic halo objects. However, such a low age can be confirmed...

    The Metallicity of Pregalactic Globular Clusters: The Observational Consequences of the First Stars
    We explore a scenario in which metal-poor globular clusters (GCs) are enriched by the first supernovae in the universe. If the first stars in a 107 Msolar dark...

    The metallicity-period-mass diagram of low-mass exoplanets
    The number of exoplanet detections continues to grow following the development of better instruments and missions. Key steps for the understanding of these...

    The methane ice rich surface of large TNO 2005 FY_9: a Pluto-twin in the trans-neptunian belt?
    Context: .The population of known large trans-neptunian objects (TNOs) is growing very fast and the knowledge of their physical properties is a key issue to...

    The Mice at play in the CALIFA survey. A case study of a gas-rich major merger between first passage and coalescence
    We present optical integral field spectroscopy (IFS) observations of the Mice, a major merger between two massive (≳1011 M⊙) gas-rich spirals NGC 4676A and B...
