CASSISI, SantiSantiCASSISI2020-04-032020-04-03201597811070788401743-9213http://hdl.handle.net/20.500.12386/23817In these last years a huge amount of both spectroscopical and photometric data has provided a plain evidence of the fact that Galactic globular clusters (GCs) host various stellar sub-populations characterized by peculiar chemical patterns. The need of properly interpreting the various observational features observed in the Color-Magnitude Diagrams (CMDs) of these stellar systems requires a new generation of stellar models properly accounting for these chemical peculiarities both in the stellar model computations and in the color - T<SUB>eff</SUB> transformations. In this review we discuss the evolutionary framework that is mandatory in order to trace the various sub-populations in any given GC.STAMPAenConference paper10.1017/S17439213140056142-s2.0-84981287602https://www.cambridge.org/core/journals/proceedings-of-the-international-astronomical-union/article/multiple-stellar-populations-the-evolutionary-framework/DA94767804F0B3CB484C2260FCE932FB2015HiA....16..245CFIS/05 - ASTRONOMIA E ASTROFISICA
