Stellar evolution in clusters and galaxies
The comparison of numerical models of stellar evolution to observations of star clusters provides useful information about such star systems. Computer models are constructed for stars with masses ranging from 0.5 to 30 Mass{sub sun} and metallicities from Z = 0.0001 to Z = 0.030. These stellar models are then used to construct isochrones and synthetic cluster diagrams of 5 open clusters (pleadies, M 11, IC 4756, NGC 1817 and Hyades). Models are also constructed for 4 globular clusters (47 Tuc, M 13, M 68 and M 15) and 4 nearby galaxies (LMC, Sculptor, Draco and SMC). Values obtained for the distance, interstellar reddening, metallicity, age and observational scatter for each cluster or galaxy are summarized in the results.
