Evolution of dwarf galaxies in the Centaurus A group

We consider star formation properties of dwarf galaxies in Cen A group observed within our HST/ACS projects number 9771 and 10235. We model color-magnitude diagrams of the galaxies under consideration and measure star formation rate and metallicity dependence on time. We study environmental dependence of the galaxy evolution and probable origin of the dwarf galaxies in the group.Comment: To appear in proceedings IAU Symp 244, 'Dark Galaxies and Lost Baryons', June 200
