We measured the ionized-gas and stellar kinematics along the major and minoraxis of a sample of 10 early-type spirals. Much to our surprise we found aremarkable gas velocity gradient along the minor axis of 8 of them. Accordingto the kinematic features observed in their ionized-gas velocity fields, wedivide our sample galaxies in three classes of objects. (i) NGC 4984, NGC 7213,and NGC 7377 show an overall velocity curve along the minor axis withoutzero-velocity points, out to the last measured radius, which is interpreted asdue to the warped structure of the gaseous disk. (ii) NGC 3885, NGC 4224, andNGC 4586 are characterized by a velocity gradient along both major and minoraxis, although non-zero velocities along the minor axis are confined to thecentral regions. Such gas kinematics have been explained as being due tonon-circular motions induced by a triaxial potential. (iii) NGC 2855 and NGC7049 show a change of slope of the velocity gradient measured along the majoraxis (which is shallower in the center and steeper away from the nucleus), aswell as non-zero gas velocities in the central regions of the minor axis. Thishas been attributed to the presence of a kinematically-decoupled gaseouscomponent in orthogonal rotation with respect to the galaxy disk, namely aninner polar disk. The case and origin of inner polar disks are discussed andthe list of their host galaxies is presented.Comment: 13 pages. 3 PostScript figures (Figs. 1 and 3 at lower resolution).
