The age structure of the Milky Way's halo
(2016)
We present a new, high-resolution chronographic (age) map of the Milky Way's halo, based on the inferred ages of similar to 130,000 field blue horizontal-branch (BHB) stars with photometry from the Sloan Digital Sky Survey. ...
Effect of diet and type of pregnancy on plasma metabolic response in sheep and its further effect on lamb performance
(2019)
This trial evaluated the individual and interactional effects of diet and type of pregnancy (twin or single) on plasma metabolic response in ewes and their lambs from late pre-partum to late post-partum. Thus, a flock of ...
The helium content of globular clusters: light element abundance correlations and HB morphology. I. NGC 6752
(2009)
Helium has been proposed as the key element to interpret the observed multiple main sequences (MS), subgiant branches (SGB) and red giant branches (RGB), as well as the complex horizontal branch (HB) morphology in Globular ...
VLT-FLAMES analysis of 8 giants in the bulge metal-poor globular cluster NGC 6522: oldest cluster in the Galaxy?. Analysis of 8 giants in NGC 6522
(2009)
Context. NGC 6522 has been the first metal-poor globular cluster identified in the bulge by Baade. Despite its importance, very few high-resolution abundance analyses of stars in this cluster are available. The bulge ...
High-resolution abundance analysis of red giants in the metal-poor bulge globular cluster HP 1
(2016)
Context. The globular cluster HP 1 is projected at only 3 degrees.33 from the Galactic center. Together with its distance, this makes it one of the most central globular clusters in the Milky Way. It has a blue horizontal ...
