Spectroscopic Confirmation: Fast rotators in the young clusters NGC 1856 and NGC 1953
Paul I. Cristofari, Andrea K. Dupree, Antonino P. Milone +2
We present the results of a spectroscopic investigation of two Large Magellanic Cloud globular clusters, NGC 1953 and NGC 1856. Both clusters have similar ages (250 and 300 Myr, re…
New Field OB and OBe Binaries of the SMC Wing: Observational Properties and Population Modeling
Irene Vargas-Salazar, M. S. Oey, Jan J. Eldridge +9
We present a radial velocity (RV) survey of the field OB and OBe stars of the SMC Wing. We use multi-epoch observations of 55 targets obtained with the Magellan IMACS and M2FS mult…
Rotation and H emission in a young SMC cluster: a spectroscopic view of NGC 330
Paul I. Cristofari, Andrea K. Dupree, Antonino P. Milone +4
We present an analysis of high-resolution optical spectra recorded for 30 stars of the split extended main-sequence turnoff (eMSTO) of the young ( 40 Myr) Small Magellanic Cl…
Abundances of Neutron-Capture Elements in 62 Stars in the Globular Cluster Messier 15
Jonathan Cabrera Garcia, Charli M. Sakari, Ian U. Roederer +7
M15 is a globular cluster with a known spread in neutron-capture elements. This paper presents abundances of neutron-capture elements for 62 stars in M15. Spectra were obtained wit…
Driving factors behind multiple populations
Ruoyun Huang, Baitian Tang, Chengyuan Li +9
Star clusters were historically considered simple stellar populations, with all stars sharing the same age and initial chemical composition. However, the presence of chemical anoma…
