Stellar models of multiple populations in globular clusters - I. The main sequence of NGC 6752

Dotter, Aaron; Ferguson, Jason W; Conroy, Charlie; Milone, Antonino; Marino, Anna; Yong, David


We present stellar atmosphere and evolution models of main-sequence stars in two stellar populations of the Galactic globular cluster NGC 6752. These populations represent the two extremes of light-element abundance variations in the cluster. NGC 6752 is a benchmark cluster in the study of multiple stellar populations because of the rich array of spectroscopic abundances and panchromatic Hubble Space Telescope photometry. The spectroscopic abundances are used to compute stellar atmosphere...[Show more]
