    AGB dust and gas ejecta in extremely metal-poor environments
    We present asymptotic giant branch (AGB) models of metallicity Z = 10-4 and 3 × 10-4, with the aim of understanding how the gas enrichment and the dust...
  • Publication
    AGB Stars and Their Circumstellar Envelopes. I. the VULCAN Code
    The interplay between AGB interiors and their outermost layers, where molecules and dust form, is a problem of high complexity. As a consequence, physical...
  • Publication
    AGB Stars and Their Circumstellar Envelopes: An Operative Approach to Computing Their Atmospheres
    The study of AGB stars necessarily covers a wide range of topics, from the primary astronomical observations to their interpretation in terms of fundamental...
  • Publication
    AGB stars in the SMC: evolution and dust properties based on Spitzer observations
    We study the population of asymptotic giant branch (AGB) stars in the Small Magellanic Cloud (SMC) by means of full evolutionary models of stars of mass 1 M⊙ ≤...

    AGC 226178 and NGVS 3543: Two Deceptive Dwarfs toward Virgo
    The two sources AGC 226178 and NGVS 3543, an extremely faint, clumpy, blue stellar system and a low surface brightness dwarf spheroidal, are adjacent systems in...
  • Publication
    Age and helium content of the open cluster NGC 6791 from multiple eclipsing binary members. II. Age dependencies and new insights
    Context. Models of stellar structure and evolution can be constrained by measuring accurate parameters of detached eclipsing binaries in open clusters. Multiple...
  • Publication
    Age-resolved chemistry of red giants in the solar neighbourhood
    In the age of high-resolution spectroscopic stellar surveys of the Milky Way, the number of stars with detailed abundances of multiple elements is rapidly...
  • Publication
    AGN feedback can produce metal enrichment on galaxy scales
    Context. Giant (> 100 kpc) nebulae associated with active galaxies provide rich information about the circumgalactic medium around galaxies, its link with the...

    Alone on a wide wide sea. The origin of SECCO 1, an isolated star-forming gas cloud in the Virgo cluster*†‡
    SECCO 1 is an extremely dark, low-mass (M⋆ ≃ 105 M⊙), star-forming stellar system lying in the low-velocity cloud (LVC) substructure of the Virgo cluster of...
