Abstract We have studied the velocity field of the Blue Compact Dwarf galaxy Mrk86 using an Hα Fabry-Perot image and 14 long-slit optical spectra. From the ionized gas velocities measured we have found that Mrk86 follows a solid-body rotation law with a central angular velocity of 34 ± 5 km s-1 kpc-1. The comparison of the modeled rotation curve with our velocity data indicates a clear dominance of the stellar mass component over the dark matter. Related with the galaxy most intense star forming knot, a very strong gradient steeping is observed. Finally, we give kinematic evidence for the Mrk86-C expanding bubble.
