Age as a Major Factor in the Onset of Multiple Populations in Stellar Clusters
S. Martocchia, I. Cabrera-Ziri, C. Lardo +16
It is now well established that globular clusters (GCs) exhibit star-to-star light-element abundance variations (known as multiple stellar populations, MPs). Such chemical anomalie…
The Search for Multiple Populations in Magellanic Cloud Clusters III: No evidence for Multiple Populations in the SMC cluster NGC 419
S. Martocchia, N. Bastian, C. Usher +16
We present the third paper about our ongoing HST survey for the search for multiple stellar populations (MPs) within Magellanic Cloud clusters. We report here the analysis of NGC 4…
A Gaia-PS1-SDSS (GPS1) Proper Motion Catalog Covering 3/4 of the Sky
Hai-Jun Tian, Prashansa Gupta, Branimir Sesar +7
We combine Gaia DR1, PS1, SDSS and 2MASS astrometry to measure proper motions for 350 million sources across three-fourths of the sky down to a magnitude of \,. Using po…
