Elliptical galaxies under perturbation

Astrophysics and Space Science, 1986
Three experiments on the initially slightly flattened spheroids (e = 0.45) have been made. The first one is run without perturbation and the others with perturbation. The results have shown that the spheroid without perturbation will evolve to nearly sphere and the other two will almost keep the originally projected shape after perturbation and ...

On the shape of elliptical galaxies

Journal of Astrophysics and Astronomy, 1983
We propose a test for the existence of prolate elliptical galaxies based on the properties of the photometric parameters introduced in the Cordoba surface photometry.

Origin of the Structure Difference Between Elliptical Galaxies and Dwarf Elliptical Galaxies

1999
According to the observations of nearby elliptical galaxies, there is a clear distinction in structural and chemical quantities between dwarf ellipticals and normal ellipticals in spite of their morphological similarity. The central concentration of dwarf ellipticals is relatively low and their luminosity profiles are best fitted by an exponential ...

Ellipticity and twisting of isophotes in elliptical galaxies

1979
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.
