Abstract
We have analyzed luminosity profiles of elliptical galaxies studied by Strom and Strom in six clusters of galaxies. We have found a relationship between the effective radius, luminosity and surface brightness for galaxies in each of these clusters. Moreover, there is a dependence of the zero point of the relation with local density of galaxies: re α σproy-0.40L0.445Ie-0.413 This relationship implies that: i) There is not a universal luminosity profile for E galaxies, ii) The environmental variation of the effective radius is larger than that produced by mergers of galaxies; iii) The distance to a galaxy can be estimated from the apparent magnitude, surface brightness, angular size and apparent local density of galaxies. The full version of this paper will be published elsewhere.
