    The Afterglows of Swift-era Gamma-Ray Bursts. II. Type I GRB versus Type II GRB Optical Afterglows
    Gamma-ray bursts (GRBs) have been separated into two classes, originally along the lines of duration and spectral properties, called "short/hard" and "long/soft...

    The AG Carinae nebula: abundant evidence for a red supergiant progenitor?
    AG Carinae is a massive, evolved supergiant which is thought to be in transition from an O star to a Wolf-Rayet (WR) star and is currently identified as a...

    The age decay of stellar magnetic activity in MS field solar-type stars
    The age decay of two indicators of the stellar magnetic activity (λ2800 Mg II emission flux and λ10830 He I equivalent width) have been studied for field solar...

    The age of extremely red and massive galaxies at very high redshift
    Aims: We present a determination of the intrinsic colors and ages of galaxies at very high redshift, in particular old galaxies (OGs) within extremely red...

    The age of the carina young association and potential membership of HD 95086
    Carina is a nearby young stellar association. So far, only a small number of stars have been clearly identified as members of this association. In this paper...

    The age-chemical abundance structure of the Galactic disc - II. α-dichotomy and thick disc formation
    We extend our previous work on the age-chemical abundance structure of the Galactic outer disc to the inner disc (4 < r < 8 kpc) based on the SDSS/APOGEE survey...
  • Publication
    The age-chemical abundance structure of the Galaxy I: evidence for a late-accretion event in the outer disc at z ∼ 0.6
    We investigate the age-chemical abundance structure of the outer Galactic disc at a galactocentric distance of r > 10 kpc as recently revealed by the SDSS...

    The age-mass relation for chromospherically active binaries. II. Lithium depletion in dwarf components.
    We present an extensive study of lithium abundances in dwarf components of chromospherically active binary stars (CABS). Since most of these binaries have known...

    The age-mass relation for chromospherically active binaries. III. Lithium depletion in giant components
    We present a study of the lithium abundances of a sample of evolved components of Chromospherically Active Binary Systems. We show that a significant part of...
