Abstract
We measured the velocity curve and the velocity dispersion profile of the ionized gas along the major axis of the edge-on galaxy UGC 10205. The observed kinematics extends up to about 40 '' from the nucleus. In the inner +/-13 '' of this early-type spiral three kinematically dist inct gaseous components are present. We disentangle a fast-rotating an d a slow-rotating component. They give to the UGC 10205 velocity curve a ''figure-of-eight'' appearance. A third velocity component is also detected on the southeast side of the galaxy. Possibly it is produced by gas in non-circular motions.
