    Accretion and outflow in V404 Cyg
    We study the optical evolution of the 2015 outburst in V404 Cyg, with emphasis on the peculiar nebular phase and subsequent decay to quiescence. From the decay...

    Adding the s-Process Element Cerium to the APOGEE Survey: Identification and Characterization of Ce ii Lines in the H-band Spectral Window
    Nine Ce ii lines have been identified and characterized within the spectral window observed by the Apache Point Observatory Galactic Evolution Experiment...

    Advancing the accuracy in age determinations of old-disk stars using an oscillating red giant in an eclipsing binary
    Context. The study of resonant oscillation modes in low-mass red giant branch stars enables us to infer their ages with exceptional (∼10%) precision. This...

    Adventures of a tidally induced bar
    Using N-body simulations, we study the properties of a bar induced in a discy dwarf galaxy as a result of tidal interaction with the Milky Way. The bar forms at...

    After the Kepler supernova explosion, no survivors were left behind
    A study involving a researcher from the Instituto de Astrofísica de Canarias (IAC), which has been led by a researcher at the Instituto de Física Fundamental...

    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...

    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⊙ ≤...
