    Disentangling the Galactic Halo with APOGEE. II. Chemical and Star Formation Histories for the Two Distinct Populations
    The formation processes that led to the current Galactic stellar halo are still under debate. Previous studies have provided evidence for different stellar...

    Disentangling the spatial substructure of Cygnus OB2 from Gaia DR2
    For the first time, we have explored the spatial substructure of the Cygnus OB2 association using parallaxes from the recent second Gaia data release. We find...

    Disk stars in the Milky Way detected beyond 25 kpc from its center
    Context. The maximum size of the Galactic stellar disk is not yet known. Some studies have suggested an abrupt drop-off of the stellar density of the disk at...

    Disk-like Chemistry of the Triangulum-Andromeda Overdensity as Seen by APOGEE
    The nature of the Triangulum-Andromeda (TriAnd) system has been debated since the discovery of this distant, low-latitude Milky Way (MW) overdensity more than a...

    Dissecting the binary cores of a planetary nebula: a novel view of chemical abundances and gas kinematics
    We propose a joint theoretical and observational project aimed to probe the link between binary central stars of planetary nebulae (PNe) and the chemical...
  • Publication
    Dissecting the Spitzer colour-magnitude diagrams of extreme Large Magellanic Cloud asymptotic giant branch stars
    We trace the full evolution of low- and intermediate-mass stars (1 ≤ M ≤ 8 M⊙) during the asymptotic giant branch (AGB) phase in the Spitzer two-colour and...

    Dissecting the stellar content of Leo I: a dwarf irregular caught in transition
    Leo I is considered one of the youngest dwarf spheroidals (dSph) in the Local Group. Its isolation, extended star formation history (SFH), and recent...

    Distance and reddening of the Local Group dwarf irregular galaxy NGC 6822
    On the basis of a new photometric analysis of the Local Group dwarf irregular galaxy NCG 6822 based on observations obtained with the Advanced Camera for...

    Distribution of red clump stars does not support the X-shaped Galactic bulge
    Context. Claims of an X-shaped Galactic bulge were based on the assumption of red clump stars as standard candles in some lines of sight crossing the off-plane...
