E. ; Strom, K. M. Abstract Gravitational encounters in dense clusters may significantly alter the structural properties of elliptical galaxies. Observational data presented in this paper suggest that ellipticals located near the dense central regions of spiral-poor and cD clusters of galaxies may lose up to 50% of their initial mass, while their characteristic sizes may decrease by a factor of 1.5 or more. These results, when compared with numerical simulations of galaxy encounters, lend support to the view that tidal stripping of halo stars is a plausible cause of these changes. The observable properties of E galaxies that are located in lower-density spiral-rich clusters appear to be relatively homogeneous and show no evidence of the effects of gravitational encounters.
