Star formation history of low surface brightness galaxies in the HDFS

Zusammenfassung

I presented the first study of the SFH of LSB galaxies by using integrated spectra. The analyzed sample was derived during a search for LSBs in the HDFS. The selection was done using a new method based on the locations of the galaxies in the colorcolor diagrams. As shown by Haberzettl (1999), the LSB galaxies in the colorcolor diagrams do not follow the redshift tracks built by the HSB galaxies. In the colorcolor diagrams, these tracks represent the five standard Hubble types. The different locations of the selected LSB galaxies are a first hint for their different stellar population mix ...
