cds-question@unistra.frglobular-star-clustersvisible-astronomymedium-band-photometryWe present Stroemgren photometry of the Galactic Globular Cluster M3 to study its multiple generations phenomenon. The use of different colour-magnitude diagrams (CMDs) and especially of the notoriously efficient c_y_ index allowed us to detect a double red giant branch in the cluster CMD. After decontamination from fore- and background sources, the two sequences turned out to be equally populated. The two components also show a bimodal radial distribution well corresponding to that predicted by numerical simulations for clusters living in an intermediate dynamical evolutive state and with a population with modified chemical composition that was born more centrally concentrated than the primordial. The analysis of high-resolution spectra quantitatively demonstrates that the two detected sequences correspond to the first (Na-poor) generation and the second (Na-rich) generation, thus confirming the importance of synergy between photometry and spectroscopy.2016MNRAS.458.4162Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/458/4162CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/278 : Catalog of stars in M3 (von Zeipel, 1908)J/A+A/290/69 : M3 photographic photometry (Buonanno+, 1994)J/PAZh/20/693 : Identification & coordinates in NGC 5272 (Evstigneeva+ 1994)J/AJ/108/1786 : M3 blue stragglers and variable stars (Guhathakurta+, 1994)J/A+A/320/757 : M3 stars CCD photometry (Ferraro+ 1997)J/A+A/324/915 : Blue stragglers in M3 (Ferraro+ 1997)J/AJ/120/1364 : Abundances in M3 and M13 (Cavallo+, 2000)J/AJ/122/3219 : M3 and M13 CCD BV photometry (Rey+, 2001)J/AJ/129/267 : RR Lyrae variables in NGC 5272 (Cacciari+, 2005)J/AJ/129/303 : Abundances of stars in M3 and M13 (Cohen+, 2005)J/AJ/129/1596 : BVI photometric variability survey of M3 (Hartman+, 2005)J/MNRAS/372/1657 : BVI(c) light curves of variables in M3 (Benko+, 2006)J/AJ/139/2300 : BVIc light curves of 3 type II Cepheids (Rabidoux+, 2010)J/MNRAS/419/2173 : Long-term photometry of M3 RR Lyrae (Jursik+, 2012)J/A+A/566/A58 : Radial velocities in M3, M13, and M92 (Kamann+, 2014)J/AJ/150/129 : Swift UVOT stars survey.
