Carbon stars as standard candles -- III. Un-binned maximum likelihood fitting and comparison with TRGB estimations
Javiera Parada, Jeremy Heyl, Harvey Richer +2
In the second paper of this series, we developed a new distance determination method using the median magnitude of carbon-rich asymptotic giant branch stars (CS) as standard ca…

Deep HST Imaging in 47 Tucanae: A Global Dynamical Model
J. Heyl, I. Caiazzo, H. Richer +3
Multi-epoch observations with ACS and WFC3 on HST provide a unique and comprehensive probe of stellar dynamics within 47 Tucanae. We confront analytic models of the globular cluste…
