Abstract:The modified Strömgrenuvby filter system, which has been used to investigate the spectrophotometric evolution of elliptical galaxies, is also found to be a powerful tool for the determination of stellar parameters in elliptical galaxies, especially metal content and the stellar type of the dominant population. We present an introduction to the behaviour of the filter system based on comparison to stellar libraries and then explore the results with respect to composite systems: globular clusters, spirals, and ellipticals.Paper presented at the 11th European Regional Astronomical Meetings of the IAU on lsquoNew Windows to the Universersquo, held 3–8 July, 1989, Tenerife, Canary Islands, Spain.
