The Gaia-ESO Survey Mg-Al anti-correlation in iDR4 globular clusters
(EDP SCIENCES S A, 2017)
We use Gaia-ESO (GES) Survey iDR4 data to explore the Mg-Alanti-correlation in globular clusters that were observed as calibrators, as a demonstration of the quality of Gaia-ESO Survey data and analysis. The results compare ...
On the Chemical Abundances of Miras in Clusters: V1 in the Metal-rich Globular NGC 5927
(Institute of Physics Publishing, 2018-03)
We present the first spectroscopic abundance determination of iron, α-elements (Si, Ca, and Ti), and sodium for the Mira variable V1 in the metal-rich globular cluster NGC 5927. We use high-resolution (R ∼ 28,000), high ...
