Multiple populations along the asymptotic giant branch of the globular cluster M 4
C. Lardo, M. Salaris, A. Savino +3
Nearly all Galactic globular clusters host stars that display characteristic abundance anti-correlations, like the O-rich/Na-poor pattern typical of field halo stars, together with…
The Search for Multiple Populations in Magellanic Cloud Clusters II: The Detection of Multiple Populations in Three Intermediate-Age SMC Clusters
F. Niederhofer, N. Bastian, V. Kozhurina-Platais +14
This is the second paper in our series about the search for multiple populations in Magellanic Cloud star clusters using the Hubble Space Telescope. Here we report the detection of…
The Search for Multiple Populations in Magellanic Cloud Clusters I: Two Stellar Populations in the Small Magellanic Cloud Globular Cluster NGC 121
F. Niederhofer, N. Bastian, V. Kozhurina-Platais +14
We started a photometric survey using the WFC3/UVIS instrument onboard the Hubble Space Telescope to search for multiple populations within Magellanic Cloud star clusters at variou…
Evidence for multiple populations in the intermediate age cluster Lindsay 1 in the SMC
K Hollyhead, N Kacharov, C Lardo +6
Lindsay 1 is an intermediate age (approx 8 Gyr) massive cluster in the Small Magellanic Cloud (SMC). Using VLT FORS2 spectra of 16 probable cluster members on the lower RGB of the…
Lost and found: evidence of Second Generation stars along the Asymptotic Giant Branch of the globular cluster NGC 6752
E. Lapenna, C. Lardo, A. Mucciarelli +7
We derived chemical abundances for C, N, O, Na, Mg and Al in 20 asymptotic giant branch (AGB) stars in the globular cluster NGC 6752. All these elements (but Mg) show intrinsic sta…
