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…
Differences in the rotational properties of multiple stellar populations in M 13: a faster rotation for the "extreme" chemical subpopulation
M. J. Cordero, V. Hénault-Brunet, C. A. Pilachowski +3
We use radial velocities from spectra of giants obtained with the WIYN telescope, coupled with existing chemical abundance measurements of Na and O for the same stars, to probe the…
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…
Light-Element Abundances of Giant Stars in the Globular Cluster M71 (NGC 6838)
Maria J. Cordero, Catherine A. Pilachowski, Christian I. Johnson +1
Aluminum is the heaviest light element displaying large star--to--star variations in Galactic globular clusters (GCs). This element may provide additional insight into the origin o…
AGB Sodium Abundances in the Globular Cluster 47 Tucanae (NGC 104)
Christian I. Johnson, Iain McDonald, Catherine A. Pilachowski +8
A recent analysis comparing the [Na/Fe] distributions of red giant branch (RGB) and asymptotic giant branch (AGB) stars in the Galactic globular cluster NGC 6752 found that the rat…
