Title: The composition of Low Surface Brightness Galaxies

Abstract: During the last years it has become clear that a large fraction of the galaxy population consists of LSB galaxies. To understand galaxy formation and evolution as a whole, it is therefore necessary to learn more about how star formation processes occur in these galaxies. For this we propose spectroscopic investigation of a sample of 17 LSB galaxies to extract spectral energy distributions (SED) in the range of 3700 A to 7400 A. Comparing these SEDs with synthetic spectra we plan to derive the stellar population mix and star formation histories in order to explain the different location of LSB galaxies in the color-color diagrams. Analyzing the emission lines using R_23 (strong line) method and diagnostic diagrams we get informations about the physical processes in the interstellar medium.
