J/AJ/136/2259       HST photometry of stars in NGC 2419    (Sandquist+, 2008)

Evolved stars in the core of the massive globular cluster NGC 2419. Sandquist E.L., Hess J.M. <Astron. J., 136, 2259-2285 (2008)> =2008AJ....136.2259S
ADC_Keywords: Clusters, globular ; Populations, stellar ; Photometry, HST Keywords: globular clusters: individual (NGC 2419) - stars: evolution - stars: horizontal-branch - stars: luminosity function, mass function - stars: mass loss Abstract: We present an analysis of optical and ultraviolet Hubble Space Telescope photometry for evolved stars in the core of the distant massive globular cluster NGC 2419. We characterize the horizontal branch (HB) population in detail including corrections for incompleteness on the long blue tail. The majority of the HB stars can be identified with two main groups (one slightly bluer than the instability strip, and the other at the extreme end of the HB). We present a method for removing (to first-order) lifetime effects from the distribution of HB stars to facilitate more accurate measurements of helium abundance for clusters with blue HBs and to clarify the distribution of stars reaching the zero-age HB.
