WOCS XCV: NGC 7789: The Evolution of Li, Stellar Rotation, and Extended Main-sequence Turnoff

Precision UBVRI photometry of NGC 7789 is combined with Gaia data to map reddening variations across the cluster face. Hydra spectra, Gaia astrometry, and isochrone fitting constrain the absolute reddening, apparent modulus, and age, respectively, to E ( B – V ) = 0.30 ± 0.02, ( m  −  M ) = 12.51 ± ...
