Formation and Evolution of Blue Stragglers in 47 Tucanae
Javiera Parada, Harvey Richer, Jeremy Heyl +2
Blue stragglers (BSS) are stars whose position in the Color-Magnitude Diagram (CMD) places them above the main sequence turn-off (TO) point of a star cluster. Using data from the c…
Dynamical estimate of post main sequence stellar masses in 47 Tucanae
Javiera Parada, Harvey Richer, Jeremy Heyl +2
We use the effects of mass segregation on the radial distribution of different stellar populations in the core of 47 Tucanae to find estimates for the masses of stars at different…
Constraining white dwarf structure and neutrino physics in 47 Tucanae
Ryan Goldsbury, Jeremy Heyl, Harvey Richer +2
We present a robust statistical analysis of the white dwarf cooling sequence in 47 Tucanae. We combine HST UV and optical data in the core of the cluster, Modules for Experiments i…
A Measurement of Diffusion in 47 Tucanae
Jeremy Heyl, Harvey B. Richer, Elisa Antolini +4
Using images from the Hubble Space Telescope Wide-Field Camera 3, we measure the rate of diffusion of stars through the core of the globular cluster 47 Tucanae using a sample of yo…
