    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...

    Galaxy-wide radio-induced feedback in a radio-quiet quasar
    We report the discovery of a radio-quiet type 2 quasar (SDSS J165315.06+234943.0 nicknamed the `Beetle' at z = 0.103) with unambiguous evidence for active...

    Gas and dust from solar metallicity AGB stars
    We study the asymptotic giant branch (AGB) evolution of stars with masses between 1 M⊙and8.5 M⊙. We focus on stars with a solar chemical composition, which...

    Gas-phase Fe/O and Fe/N abundances in star-forming regions: Relations between nucleosynthesis, metallicity, and dust
    Context. In stars, metallicity is usually traced using Fe, while in nebulae, O serves as the preferred proxy. Both elements have different nucleosynthetic...

    Generalized T<SUB>e</SUB>([O III])–T<SUB>e</SUB>(He I) Discrepancies in Ionized Nebulae: Possible Evidence of Case B Deviations and Temperature Inhomogeneities
    The physics of recombination lines in the He I singlet system is expected to be relatively simple, supported by accurate atomic models. We examine the...

    Geometry of the Draco C1 Symbiotic Binary
    Draco C1 is a known symbiotic binary star system composed of a carbon red giant and a hot, compact companion—likely a white dwarf—belonging to the Draco dwarf...
