Blue straggler star populations in globular clusters. II. Proper-motion cleaned HST catalogues of BSSs in 38 Galactic GCs. Simunovic M., Puzia T.H. <Mon. Not. R. Astron. Soc., 462, 3401-3418 (2016)> =2016MNRAS.462.3401S (SIMBAD/NED BibCode)
ADC_Keywords: Clusters, globular ; Proper motions Keywords: proper motions - blue stragglers - globular clusters: general Abstract: We present new blue straggler star (BSS) catalogues in 38 Milky Way globular clusters (GCs) based on multipassband and multi-epoch treasury survey data from the Hubble Space Telescope. We measure precise astrometry and relative proper motions of stars in all target clusters and performed a subsequent cluster membership selection. We study the accuracy of our proper-motion measurements using estimates of central velocity dispersions and find very good agreement with previous studies in the literature. Finally, we present a homogeneous BSS selection method, that expands the classic BSS selection parameter space to more evolved BSS evolutionary stages. We apply this method to the proper-motion cleaned GC star catalogues in order to define proper-motion cleaned BSS catalogues in all 38 GCs, which we make publicly available to enable further study and follow-up observations. Description: We present a comprehensive proper-motion analysis based on HST observations of 38 Galactic GCs obtained by two public treasury surveys ('The ACS Globular Cluster Survey', GO-10775, see Sarajedini et al., 2007AJ....133.1658S, and 'The HST Legacy Survey of Galactic Globular Clusters: Shedding UV Light on Their Populations and Formation', GO-13297, see Piotto et al.. 2015AJ....149...91P).
