The study of the ellipticity profiles in a sample of elliptical galaxies and the analysis of previous results makes it possible to establish a classification scheme in five classes as follows: increasing ellipticity, decreasing, with maximum, with minimum and constant. The phenomenon of the change of the direction of the major axis of the isophotes is discussed and some examples are presented.

Abstract

The study of the ellipticity profiles in a sample of elliptical galaxies and the analysis of previous results makes it possible to establish a classification scheme in five classes as follows: increasing ellipticity, decreasing, with maximum, with minimum and constant. The phenomenon of the change of the direction of the major axis of the isophotes is discussed and some examples are presented.
