| Abstract: |
A sample of galaxies characterized by a low surface brightness disk has dynamically studied using, as tracer, the stellar component. The kinematical data, taken along the major and minor axis, extend well within the disk region. The stellar kinematics is more regular and symmetric than the ionized-gas kinematics. Moreover, when comparing the circular velocity derived by means of the dynamical mass model and the one measured from the ionized-gas we find that the later is characterized by a shallower velocity gradient in the central regions. |
