    Horizontal Branch Morphology and Multiple Stellar Populations in the Anomalous Globular Cluster M 22
    M 22 is an anomalous globular cluster that hosts two groups of stars with different metallicity and s-element abundance. The star-to-star light-element...

    Horizontal branch morphology: A new photometric parametrization
    Context. Theory and observations indicate that the distribution of stars along the horizontal branch of Galactic globular clusters mainly depends on the metal...

    Hot bottom burning and s-process nucleosynthesis in massive AGB stars at the beginning of the thermally-pulsing phase
    We report the first spectroscopic identification of massive Galactic asymptotic giant branch (AGB) stars at the beginning of the thermal pulse (TP) phase. These...

    How many components? Quantifying the complexity of the metallicity distribution in the Milky Way bulge with APOGEE
    We use data of ∼13-=000 stars from the Sloan Digital Sky Survey/Apache Point Observatory Galactic Evolution Experiment survey to study the shape of the bulge...

    How well can we unravel the accreted constituents of the Milky Way stellar halo?: A test on cosmological hydrodynamical simulations
    Context. One of the primary goals of Galactic Archaeology is to reconstruct the Milky Way's accretion history. To achieve this, significant efforts have been...
