The metal-rich abundance pattern - spectroscopic properties and abundances for 107 main-sequence stars
(Oxford university press, 2017)
We report results from the high-resolution spectral analysis of the 107 metal-rich (mostly [Fe/H] >= 7.67 dex) target stars from the Calan Hertfordshire Extrasolar Planet Search programme observed with HARPS. Using our ...

OXYGEN ABUNDANCES IN LOW- AND HIGH-alpha FIELD HALO STARS AND THE DISCOVERY OF TWO FIELD STARS BORN IN GLOBULAR CLUSTERS
(IOP PUBLISHING LTDBRISTOL, 2012)
Oxygen abundances of 67 dwarf stars in the metallicity range -1.6 < [Fe/H] < -0.4 are derived from a non-LTE analysis of the 777 nm O I triplet lines. These stars have precise atmospheric parameters measured by Nissen ...
A detailed study of lithium in 107 CHEPS dwarf stars
(EDP Sciences, 2018)
Context. We report results from lithium abundance determinations using high resolution spectral analysis of the 107 metal-rich stars from the Calan-Hertfordshire Extrasolar Planet Search programme.
Aims. We aim to set ...
The Origins of Young Stars in the Direction of the Leading Arm of the Magellanic Stream: Abundances, Kinematics, and Orbits
(Institute of Physics Publishing, 2019)
We explore the origins of the young B-type stars found by Casetti-Dinescu et al. at the outskirts of the Milky Way disk in the sky region of the Leading Arm of the Magellanic Stream. High-resolution spectroscopic observations ...
