    A very dark stellar system lost in Virgo: kinematics and metallicity of SECCO 1 with MUSE
    We present the results of VLT-MUSE (Very Large Telescope-Multi Unit Spectroscopic Explorer) integral field spectroscopy of SECCO 1, a faint, star-forming...

    A view of the H-band light-element chemical patterns in globular clusters under the AGB self-enrichment scenario
    We discuss the self-enrichment scenario by asymptotic giant branch (AGB) stars for the formation of multiple populations in globular clusters (GCs) by analysing...

    A WFC3/HST View of the Three Stellar Populations in the Globular Cluster NGC 6752
    Multi-band Hubble Space Telescope photometry reveals that the main sequence, sub-giant, and the red-giant branch of the globular cluster NGC 6752 splits into...

    Abell 30 - A binary central star among the born-again planetary nebulae
    Eight planetary nebulae have been identified as 'born-again', a class of object typified by knotty secondary ejecta having low masses (${\sim}10^{-4}$ M ☉) with...

    About Metallicity Variations in the Local Galactic Interstellar Medium
    In this paper we discuss and confront recent results on metallicity variations in the local interstellar medium, obtained from observations of H II regions and...

    Absence of an X-shaped Structure in the Milky Way Bulge Using Mira Variable Stars
    The stellar density distribution of the bulge is analyzed through one of its tracers. We use oxygen-rich Mira variables from the Catchpole et al. survey and...

    Absence of significant cross-correlation between WMAP and SDSS
    Aims: Several authors have claimed to detect a significant cross-correlation between microwave WMAP anisotropies and the SDSS galaxy distribution. We repeat...

    Abundances, Stellar Parameters, and Spectra from the SDSS-III/APOGEE Survey
    The SDSS-III/Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey operated from 2011–2014 using the APOGEE spectrograph, which collects high...

    Accretion and outflow in V404 Cyg
    We study the optical evolution of the 2015 outburst in V404 Cyg, with emphasis on the peculiar nebular phase and subsequent decay to quiescence. From the decay...
