ADC_Keywords: Stars, horizontal branch ; Photometry, HST ; Clusters, globular Keywords: binaries: general - blue stragglers - stars: horizontal-branch - globular clusters: individual (NGC 2419) - stars: evolution Abstract: We have used a combination of ACS HST high-resolution and wide-field Subaru data in order to study the blue straggler star (BSS) population over the entire extension of the remote Galactic globular cluster NGC 2419. The BSS population presented here is among the largest ever observed in any stellar system, with more than 230 BSSs in the brightest portion of the sequence. The radial distribution of the selected BSSs is essentially the same as that of the other cluster stars. Description: The high-resolution set is composed of a series of public images obtained with the Wide Field Channel of the Advanced Camera for Surveys (ACS) on board the Hubble Space Telescope (HST) in F435W, F555W, and F814W filters. These are the highest resolution (∼0.05"/pixel) observations available to date for NGC 2419. The wide field set is a set of public V and I images obtained with the Subaru Prime Focus Camera (Suprime-Cam) of the 8.2m Subaru telescope at the Hawaii National Astronomical Observatory of Japan.
