Multiple stellar populations in Asymptotic Giant Branch stars of Galactic Globular Clusters
E. P. Lagioia, A. P. Milone, A. F. Marino +8
Multiple stellar populations (MPs) are a distinct characteristic of Globular Clusters (GCs). Their general properties have been widely studied among main sequence, red giant branch…
The Cluster Ages Experiment (CASE). VIII. Age and Distance of the Globular Cluster 47 Tuc from the Analysis of Two Detached Eclipsing Binaries
I. B. Thompson, A. Udalski, A. Dotter +20
We use photometric and spectroscopic observations of the eclipsing binary E32 in the globular cluster 47 Tuc to derive the masses, radii, and luminosities of the component stars. T…
Hunting for Brown Dwarfs in the Globular Cluster M4: 2nd epoch HST NIR observations
Andrea Dieball, L. R. Bedin, Christian Knigge +5
We present an analysis of the second epoch HST WFC3 F110W near-Infrared (NIR) imaging data of the globular cluster M4. The new dataset suggests that one of the previously suggested…
Chemical (in)homogeneity and atomic diffusion in the open cluster M67
F. Liu, M. Asplund, D. Yong +4
Context. The benchmark open cluster M67 is known to have solar metallicity and similar age as the Sun. It thus provides us a great opportunity to study the properties of solar twin…
Different stellar rotation in the two main sequences of the young globular cluster NGC1818: first direct spectroscopic evidence
A. F. Marino, N. Przybilla, A. P. Milone +4
We present a spectroscopic analysis of main sequence (MS) stars in the young globular cluster NGC1818 (age~40 Myrs) in the Large Magellanic Cloud. Our photometric survey on Magella…
Chemical abundances in the multiple sub-giant branch of 47 Tucanae: insights on its faint sub-giant branch component
A. F. Marino, A. P. Milone, L. Casagrande +8
The globular cluster 47 Tuc exhibits a complex sub-giant branch (SGB) with a faint-SGB comprising only about the 10% of the cluster mass and a bright-SGB hosting at least two disti…
