235. Populations in globular clusters

The occurrence of multiple stellar populations in globular clusters has been described as one of the most puzzling open issues of stellar astrophysics. I describe the problem, and demonstrate how the combination of Gaia's astrometry, and the synthetic photometry derived from its low-resolution BP/RP spectra, is helping to identify its origin.

Abstract

The occurrence of multiple stellar populations in globular clusters has been described as one of the most puzzling open issues of stellar astrophysics. I describe the problem, and demonstrate how the combination of Gaia's astrometry, and the synthetic photometry derived from its low-resolution BP/RP spectra, is helping to identify its origin.
