    Constraining gas metal mixing strength in simulations using observations of the Milky Way's disc
    This work explores the mixing rate of metals in the interstellar medium (ISM), comparing observational constraints from our solar neighbourhood to high...

    Constraining Metallicity-dependent Mixing and Extra Mixing Using [C/N] in Alpha-rich Field Giants
    Internal mixing on the giant branch is an important process which affects the evolution of stars and the chemical evolution of the galaxy. While several...

    Constraining the Epoch of Reionization from the Observed Properties of the High-z Universe
    We combine observational data on a dozen independent cosmic properties at high-z with the information on reionization drawn from the spectra of distant luminous...

    Constraining the overcontact phase in massive binary evolution. II. Period stability of known O+O overcontact systems
    Context. Given that mergers are often invoked to explain many exotic phenomena in massive star evolution, understanding the evolutionary phase directly...

    Constraining the solar neighbourhood age-metallicity relation from white dwarf-main sequence binaries
    The age-metallicity relation (AMR) is a fundamental tool for constraining the chemical evolution of the Galactic disc. In this work, we analyse the...

    Constraint on the time variation of the fine-structure constant with the SDSS-III/BOSS DR12 quasar sample
    From the Sloan Digital Sky Survey (SDSS) Data Release 12, which covers the full Baryonic Oscillation Spectroscopic Survey (BOSS) footprint, we investigate the...

    Constraints on the formation of the globular cluster IC 4499 from multiwavelength photometry
    We present new multiband photometry for the Galactic globular cluster IC 4499 extending well past the main-sequence turn-off in the U, B, V, R, I and DDO 51...

    Convective core sizes in rotating massive stars. I. Constraints from solar metallicity OB field stars
    Context. Spectroscopic studies of Galactic O and B stars show that many stars with masses above 8 M ⊙ have been observed in the Hertzsprung-Russell (HR) diagram...
  • Publicación
    Cool stars in the Galactic center as seen by APOGEE. M giants, AGB stars, and supergiant stars and candidates
    The Galactic center region, including the nuclear disk, has until recently been largely avoided in chemical census studies because of extreme extinction and...
