1. A Photometric Study of the Galactic Disks based on Strömgren Photometry
Sammanfattning : One of the key questions in todays galaxy research is the formation and evolution of disk galaxies such as the Milky Way. Using observations in the intermediate band Stromgren uvby filter system we have investigated how both density and metallicity varies within the Galactic disks in order to learn more about the Galaxy and its past.

2. Observational Studies of the Chemical Evolution in the Galactic Thin and Thick Disks
Sammanfattning : The origin and evolution of the thin and thick disks in the Galaxy have been studied by means of detailed stellar abundances. High-resolution spectra of 102 F and G dwarf stars have been obtained with the spectrographs on the ESO 3.6-m and ESO 1. LÄS MER
