    Gaia-DR2 extended kinematical maps . I. Method and application
    Context. The Gaia Collaboration has used Gaia-DR2 sources with six-dimensional (6D) phase space information to derive kinematical maps within 5 kpc of the Sun...

    Gaia-DR2 extended kinematical maps. II. Dynamics in the Galactic disk explaining radial and vertical velocities
    Context. In our Paper I, by using statistical deconvolution methods, extended kinematics maps of Gaia-DR2 data have been produced in a range of heliocentric...

    Gaia-DR2 extended kinematical maps. III. Rotation curves analysis, dark matter, and MOND tests
    Context. Recent statistical deconvolution methods have produced extended kinematical maps in a range of heliocentric distances that are a factor of two to three...

    Gaia-ESO survey: Lithium abundances in open cluster Red Clump stars
    Context. It has recently been suggested that all giant stars with masses below 2 M ⊙ suffer an episode of surface lithium enrichment between the tip of the red...
  • Publicación
    Gaia-ESO survey: Massive stars in the Carina Nebula. I. A new census of OB stars
    Context. The Carina Nebula is one of the major massive star-forming regions in the Galaxy. Its relatively nearby distance (2.35 kpc) makes it an ideal...

    Galactic archaeology with asteroseismology and spectroscopy: Red giants observed by CoRoT and APOGEE
    With the advent of the space missions CoRoT and Kepler, it has recently become feasible to determine precise asteroseismic masses and relative ages for large...

    Galactic Globular Clusters: Why should we care about them?
    Galactic globular clusters have always been at the crossroad of several investigations in both Stellar and Galactic Astrophysics. For long time, they have been...

    Galactic kinematics of Planetary Nebulae with [WC] central star
    High resolution spectra are used to analyze the galactic kinematics and distribution of a sample of planetary nebulae with [WR] and `wel' central star ([WR]PN...
