Formation and Evolution of Dwarf Elliptical Galaxy(Proceedings of Japan-France Seminar on Chemical Evolution of Galaxies with Active Star Formation)

Evolution of the dwarf elliptical galaxy is considered with special attention to gas loss from the galaxy by supernova explosion. The dwarf elliptical galaxy is modeled as a spherical ensemble of gas clouds undergoing mass loss and its structural evolution is followed by N-body simulation. A significant fraction of the initial mass should have been lost from dEs. The characteristic structure of observed dEs is naturally explained if the gas is mainly ejected from the central region of the galaxy
