Near infrared observations of globular clusters
Abstract
A long-term program intended to secure near-infrared photometry of galactic globular clusters down to the main sequence has been started since 1988. This is particularly important for checking some aspects of the theory of stellar evolution and stellar model atmosphere calculations and for getting color estimates via a simplified 'infrared flux method' (IFM) analysis. Here we briefly present the advantages of studying such objects in the infrared and list the main items which can be profitably grasped via this study.
