WebSpheroidal, pressure-supported systems with highly anisotropic velocity distributions are often unstable, relaxing to less flattened and less anisotropic configurations in a few dynamical times. Such instabilities may explain the absence of elliptical galaxies flatter than E6 or E7. ... Spherical systems (Henon, radial-orbit, & tangential-orbit ...

A spheroid, also known as an ellipsoid of revolution or rotational ellipsoid, is a quadric surface obtained by rotating an ellipse about one of its principal axes; in other words, an ellipsoid with two equal semi-diameters. A spheroid has circular symmetry. If the ellipse is rotated about its major axis, the … Zobraziť viac The equation of a tri-axial ellipsoid centred at the origin with semi-axes a, b and c aligned along the coordinate axes is $${\displaystyle {\frac {x^{2}}{a^{2}}}+{\frac {y^{2}}{b^{2}}}+{\frac {z^{2}}{c^{2}}}=1.}$$ The equation of a spheroid with z as the symmetry axis is … Zobraziť viac The most common shapes for the density distribution of protons and neutrons in an atomic nucleus are spherical, prolate, and oblate … Zobraziť viac • Media related to Spheroids at Wikimedia Commons • "Spheroid" .
