    RR Lyrae Stars and Anomalous Cepheids as Population Tracers in Local Group Galaxies
    We discuss the use and importance of pulsating variable stars as population tracers in Local Group galaxies. Among bright variable crossing the classical...

    Rubidium abundances in solar metallicity stars
    Context. Rubidium is one of the few elements produced by the neutron capture s- and r-processes in almost equal proportions. Recently, a Rb deficiency ([Rb/Fe]...

    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...
  • Publication
    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...

    Rubidium-Rich Asymptotic Giant Branch Stars
    A long-debated issue concerning the nucleosynthesis of neutron-rich elements in asymptotic giant branch (AGB) stars is the identification of the neutron source...

    Ruling out the Orbital Decay of the WASP-43b Exoplanet
    We present 15 new transit observations of the exoplanet WASP-43b in the i‧, g‧, and R filters with the 1.0 m telescopes of Las Cumbres Observatory Global...

    RXCJ1111.6+4050 galaxy cluster: Observational evidence of a transitional fossil group
    We present a detailed kinematical and dynamical study of the galaxy cluster RXCJ1111.6+4050 (RXCJ1111), at z = 0.0756 using 104 new spectroscopic redshifts of...

    RXJ 0921+4529: A Binary Quasar or a Gravitational Lens?
    We report the new spectroscopic observations of the gravitational lens RXJ 021+4529 with the multi-mode focal reducer SCORPIO of the SAO RAS 6 m telescope. The...

    S Ori J053825.4-024241: a classical T Tauri-like object at the substellar boundary
    We present a spectrophotometric analysis of S Ori J053825.4-024241, a candidate member close to the substellar boundary of the young (1-8 Myr), nearby (~360 pc)...
