    Revealing the tidal scars of the Small Magellanic Cloud
    Due to their close proximity, the Large and Small Magellanic Clouds (LMC/SMC) provide natural laboratories for understanding how galaxies form and evolve. With...

    Revised Bolometric Corrections and Interstellar Extinction Coefficients for the ACS and WFPC2 Photometric Systems
    We present extensive tables of bolometric corrections and interstellar extinction coefficients for the WFPC2 and ACS (both WFC and HRC) photometric systems...

    Revisiting the radial abundance gradients of nitrogen and oxygen of the Milky Way
    We present spectra obtained with the 10.4 m Gran Telescopio Canarias telescope of 13 Galactic H II regions, most of them of very low ionization degree. The...

    Rubidium and zirconium abundances in massive Galactic asymptotic giant branch stars revisited
    Context. Luminous Galactic OH/IR stars have been identified as massive (>4-5 M⊙) asymptotic giant branch (AGB) stars experiencing hot bottom burning and Li...

    Rubidium, zirconium, and lithium production in intermediate-mass asymptotic giant branch stars
    Context. A recent survey of a large sample of Galactic intermediate-mass (>3 M&sun;) asymptotic giant branch (AGB) stars shows that they exhibit large...
