Description
"UV properties of galactic globular clusters" we propose deep far and near-UV images OF15 galactic globular clusters (GCS) as a follow up to programs by our group in cycles 1 and 3. The final database will be the largest homogeneous dataset ever produced on the UV photometric properties of galactic GCS and will allow a full characterization of their hot stellar contents. Image size and resolution are such that excellent photometry outside the cluster cores can be obtained for statistically representative samples of all STARS that contribute relevantly to the integrated light of stellar populations in the UV. These data will be used to address the following problems: 1) a study of the UV morphology of the horizontal branch (HB), in order to shed new light on the late stage of evolution of low-mass STARS, in connection with UV-excess of early-type galaxies; 2) constraining the models for blue straggler formation from studies of the radial distribution of these objects (in combination with HST photometry of the cluster cores, obtained by our own group); 3) enlarging the known sample of rare STARS such as post-AGB and supra-HB STARS by a factor of three, bringing a major boost to the statistics of these short-lived, yet UV-relevant STARS; 4) studies of integrated uvloptical colors of galactic GCS, in order to study correlations of these integrated properties with global and structural parameters such as mass, concentration, core morphology, luminosity, age, and chemical composition. These data will provide important constraints on evolutionary models for STARS and galaxies and will help to shed new light on the problem of the UV-excess of early-type galaxies. IT will also serve as badly needed local templates against which data for distant, unresolved systems need to be contrasted.
