    Rapid Rotation of Low-mass Red Giants Using APOKASC: A Measure of Interaction Rates on the Post-main-sequence
    We investigate the occurrence rate of rapidly rotating (v{sin}i >10 km s‑1), low-mass giant stars in the Apache Point Observatory Galaxy Evolution Experiment...

    Rb-Rich Asymptotic Giant Branch Stars in the Magellanic Clouds
    We present high-resolution (R ~ 60,000) optical spectra of a carefully selected sample of heavily obscured and presumably massive O-rich asymptotic giant branch...

    Recent activity of the Be/X-ray binary system SAX J2103.5+4545
    Aims: We present a multiwavelength study of the Be/X-ray binary system SAX J2103.5+4545 with the goal of better characterizing the transient behaviour of this...

    Reconstructing the history of the Milky Way and probing the dark matter nature in WEAVE and LSST era
    At present, our understanding of the formation history of the MW is limited due to the complexity of observing the imprints of accretion events and of...

    Recovering star formation histories: Integrated-light analyses vs. stellar colour-magnitude diagrams
    Context. Accurate star formation histories (SFHs) of galaxies are fundamental for understanding the build-up of their stellar content. However, the most...

    Red giants observed by CoRoT and APOGEE: The evolution of the Milky Way's radial metallicity gradient
    Using combined asteroseismic and spectroscopic observations of 418 red-giant stars close to the Galactic disc plane (6 kpc RGal ≲ 13 kpc, | ZGal| 0.3 kpc), we...

    Red supergiant stars in binary systems. I. Identification and characterization in the small magellanic cloud from the UVIT ultraviolet imaging survey
    We aim to identify and characterize binary systems containing red supergiant (RSG) stars in the Small Magellanic Cloud (SMC) using a newly available ultraviolet...

    Red supergiants around the obscured open cluster Stephenson 2
    Context. Several clusters of red supergiants have been discovered in a small region of the Milky Way close to the base of the Scutum-Crux Arm and the tip of the...

    Reduction of the maximum mass-loss rate of OH/IR stars due to unnoticed binary interaction
    In 1981, the idea of a superwind that ends the life of cool giant stars was proposed1. Extreme oxygen-rich giants, OH/IR stars, develop superwinds with the...
