VizieR Online Data Catalog: Terzan 5 chemical and kinematical properties (Massari+, 2014)
Abstract
This study is based on a sample of 1608 stars within a radius of 800'' from the center of Terzan 5 (αJ2000=17h:48m:4.85s, δJ2000=-24°:46':44.6''; see Ferraro et al. 2009Natur.462..483F; Lanzoni et al. 2010ApJ...717..653L). While the overall survey will be described in a forthcoming paper (F. Ferraro et al., in preparation), in this work we focus on a subsample of stars representative of the field population surrounding Terzan 5. Given the value of the tidal radius of the system (rt ~ 300''; Lanzoni et al. 2010ApJ...717..653L; Miocchi et al. 2013ApJ...774..151M), we conservatively selected as genuine field population members all the targets more distant than 400'' from the center of Terzan 5. This subsample is composed of 615 stars belonging to two different data sets obtained with FLAMES (Pasquini et al. 2002Msngr.110....1P) at the ESO VLT and with DEIMOS (Faber et al. 2003SPIE.4841.1657F) at the Keck II Telescope. Each target has been selected from the ESO-Wide Field Imager (WFI) optical catalog described in Lanzoni et al. (2010ApJ...717..653L), along the brightest portion of the red giant branch (RGB), with magnitudes brighter than I<18.5.
