    Quantifying radial migration in the Milky Way: inefficient over short time-scales but essential to the very outer disc beyond 15 kpc
    Stellar radial migration plays an important role in reshaping a galaxy's structure and the radial distribution of stellar population properties. In this work...

    Radial velocities and metallicities from infrared Ca II triplet spectroscopy of open clusters . Berkeley 26, Berkeley 70, NGC 1798, and NGC 2266
    Context. Open clusters are ideal test particles for studying the formation and evolution of the Galactic disk. However, the number of clusters with information...

    Radial velocities and metallicities from infrared Ca ii triplet spectroscopy of open clusters. II. Berkeley 23, King 1, NGC 559, NGC 6603, and NGC 7245
    Context. Open clusters are key to studying the formation and evolution of the Galactic disc. However, there is a deficiency of radial velocity and chemical...

    Radial Velocities in the Outermost Disk toward the Anticenter
    We measure the mean Galactocentric radial component of the velocity of stars (v R ) in the disk at 8 kpc R 28 kpc in the direction of the anticenter. For this...

    Raman, FT-IR spectroscopy and morphology of carbon dust from carbon arc in liquid benzene
    The carbon arc in liquid benzene produces carbon dust in addition to phenylacetyene and a number of other molecular products. The carbon dust was analyzed by...

    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...
