18 Feb 1999 | | Subject: | astro-ph | | Abstract: | The kinematics of stars and ionized gas has been studied near the center of the S0 galaxy NGC 4036. Dynamical models based both on stellar photometry and kinematics have been built in order to derive the gravitational potential in which the gas is expected to orbit. The observed gas rotation curve falls short of the circular velocity curve inferred from these models. Inside 10’’ the observed gas velocity dispersion is found to be comparable to the predicted circular velocity, showing that the gas cannot be considered on circular orbits. The understanding of the observed gas kinematics is improved by models based on the Jeans Equations, which assume the ionized gas as an ensemble of collisionless cloudlets distributed in a spheroidal and in a disk component. | | Source: | arXiv, astro-ph/9902270 | | Services: | Forum | Review | PDF | Favorites | |
