    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...

    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...

    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...

    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...

    Age and metallicity gradients in early-type galaxies: a dwarf-to-giant sequence
    We studied the stellar populations of 40 early-type galaxies using medium-resolution long-slit spectroscopy along their major axes (and along the minor axis for...

    Age and metallicity gradients support hierarchical formation for M87
    In order to probe the inside-out formation of the most massive galaxies in the Universe, we have explored the radial (0.1 ≲ R ≲ 8 kpc) variation of the spectral...

    Age dating of an early Milky Way merger via asteroseismology of the naked-eye star ν Indi
    Over the course of its history, the Milky Way has ingested multiple smaller satellite galaxies 1. Although these accreted stellar populations can be...

    Age Estimates for Globular Clusters in NGC 1399
    We present high signal-to-noise Keck spectra for 10 globular clusters associated with the giant Fornax elliptical galaxy NGC 1399 and compare measured line...
