Revised stromgren metallicity calibration for red giants
(SPRINGER SCIENCE, 2000)
Red giants in open clusters. IX. NGC 2324, 2818, 3960 and 6259
(EDP Sciences, 2001-12)
We present accurate radial velocities and photoelectric UBV photometry for 73 and 57 red-giant candidates, respectively, in the intermediate-age open clusters NGC 2324, 2818, 3960 and 6259. These data confirm the membership ...
Photometric Observations of Grid Giant Star Survey Candidates
(2004)
We compare variability of radial velocity (RV) and brightness for a sam-ple of red giants which were selected as candidates for the Grid Giant StarSurvey (GGSS). The purpose of the survey is to select astrometrically sta-ble ...
Li-rich red giant branch stars in the Galactic bulge
(2009)
Aims. We present lithium abundance determination for a sample of K giant stars in the Galactic bulge. The stars presented here are the only 13 stars with a detectable lithium line (6767.18 Å) among ~400 stars for which we ...
The Aarhus red giants challenge. I. Stellar structures in the red giant branch phase
(EDP Sciences, 2020-03)
Context. With the advent of space-based asteroseismology, determining accurate properties of red-giant stars using their observed oscillations has become the focus of many investigations due to their implications in a ...
Lithium-rich giants in the Galactic thick disk
(2011)
Context: Lithium is a fragile element, which is easily destroyed in the stellar interior. The existence of lithium-rich giants still represents a challenge for stellar evolution models. Aims: We have collected a large ...
Manganese abundances in galactic bulge red giants
