Scientific paper

Intrinsic properties of elliptical galaxies and the mechanisms of their formation and evolution are discussed on the basis of high-precision, multicolor, surface photometry of 39 elliptical galaxies and measurements of rotation curves and velocity dispersion profiles. Using the data collected, a number of correlations between the characteristic parameters of the stellar population of the galaxies have been made to explore their structure and kinematics. The luminosity dependence of color gradients is a good discriminant among various models of galaxy formation. The lowest luminosity galaxies in the sample do not show any color gradients. They have boxy isophotes, and are also rotationally flattened. These properties may be related to the fact that they are companions of larger ellipsoidal systems and it could also provide an important clue to the formation of ellipticals.
