An elliptical galaxy is defined as a type of galaxy that exhibits a correlation between the velocity dispersion of its stars and its intrinsic luminosity. It is also characterized by its occupation of a 'fundamental plane' where the galaxy size is tightly correlated with the surface brightness and velocity dispersion.
An elliptical galaxy is a type of galaxy that is classified based on its shape and visual appearance. It is typically large, contains millions to trillions of stars, and lacks the spiral arms seen in spiral galaxies.
4 Αυγ 2011 · This article reviews the progress since then, providing both an historical perspective and a contemporary review of the stellar structure of bulges, discs and elliptical galaxies.
The discovery that elliptical galaxies rotate much more slowly than a fluid body with the same shape has led to a qualitative change in our understanding of the dynamics of these systems. It is now believed that elliptical galaxies are fully triaxial in shape.
17 Οκτ 2016 · Our results show that the real shape distributions of elliptical galaxies are affected by the environments of the galaxies; there are more flat elliptical galaxies in lower density regions, whereas more round elliptical galaxies are present in higher density regions.
For a long time, beginning with Hubble's original classification, elliptical galaxies were regarded as structureless, presumably rotationally flattened, gas free systems of old stars. Modern research has shown that very little of this simple description remains true.
