摘要：
Galactic globular clusters (GGCs) are extremely important astrophysical objects since (i) they are prime laboratories for testing stellar evolution; (ii) they are "fossils" from the epoch of galaxy formation, and, thus important cosmological tools; (iii) they serve as test particles for studying the dynamics of the Galaxy. A few years ago our group started a long-term project devoted to study the global stellar population in a sample of "proto-type" GGCs following a multi-wavelength approach: IR and optical observations to study cool giants and UV observations to study blue hot sequences (Horizontal Branch (1113), Blue Stragglers Stars (BSS), etc). In this paper I report a short summary of the most recent results.
