Elliptical galaxies under perturbation
Astrophysics and Space Science, 1986Three 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 ...

Hydrodynamical models of elliptical galaxies
Celestial Mechanics, 1988Hydrodynamical models of elliptical galaxies can be obtained by means of Jeans’equations (see for example Ortega and de Freitas Pacheco, 1986). Following this approach, we consider a mass distribution in steady state which approximates de Vaucouleurs’ r1/4 law, and assume the principal axes of the velocity distribution to be parallel to unitary vectors
