    The mass of our Galaxy from satellite proper motions in the Gaia era
    We use Gaia DR2 systemic proper motions of 45 satellite galaxies to constrain the mass of the Milky Way using the scale-free mass estimator of Watkins et al....

    The messy death of a multiple star system and the resulting planetary nebula as observed by JWST
    Planetary nebulae—the ejected envelopes of red giant stars—provide us with a history of the last, mass-losing phases of 90% of stars initially more massive than...

    The Metal-poor non-Sagittarius (?) Globular Cluster NGC 5053: Orbit and Mg, Al, and Si Abundances
    Metal-poor globular clusters (GCs) exhibit intriguing Al–Mg anti-correlations and possible Si–Al correlations, which are important clues to decipher the...

    The metal-rich halo tail extended in |z|: a characterization with Gaia DR2 and APOGEE
    We report an analysis of the metal-rich tail ([Fe/H] > -0.75) of stars located at distances from the Galactic plane up to |z| ˜ 10 kpc, observed by the Apache...

    The Milky Way bar and bulge revealed by APOGEE and Gaia EDR3
    We investigate the inner regions of the Milky Way using data from APOGEE and Gaia EDR3. Our inner Galactic sample has more than 26 500 stars within |X Gal|< 5...

    The Milky Way's bulge star formation history as constrained from its bimodal chemical abundance distribution
    We conduct a quantitative analysis of the star formation history (SFH) of the Milky Way's (MW) bulge by exploiting the constraining power of its stellar [Fe/H]...

    The Missing Link? Discovery of Pulsations in the Nitrogen-rich PG 1159 Star PG 1144+005
    Up to 98% of all single stars will eventually become white dwarfs-stars that link the history and future evolution of the Galaxy, and whose previous evolution...

    The Missing Satellites of the Magellanic Clouds? Gaia Proper Motions of the Recently Discovered Ultra-faint Galaxies
    According to LCDM theory, hierarchical evolution occurs on all mass scales, implying that satellites of the Milky Way should also have companions. The recent...
