    Absence of an X-shaped Structure in the Milky Way Bulge Using Mira Variable Stars
    The stellar density distribution of the bulge is analyzed through one of its tracers. We use oxygen-rich Mira variables from the Catchpole et al. survey and...

    Absence of significant cross-correlation between WMAP and SDSS
    Aims: Several authors have claimed to detect a significant cross-correlation between microwave WMAP anisotropies and the SDSS galaxy distribution. We repeat...

    Abundances, Stellar Parameters, and Spectra from the SDSS-III/APOGEE Survey
    The SDSS-III/Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey operated from 2011–2014 using the APOGEE spectrograph, which collects high...

    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...

    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...

    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...
