Abstract
I use fully selfconsistent N body simulations to discuss two specific types of interactions between a barred target galaxy and a small companion.
In the first type of interactions an expanding ring is formed, in a way similar to the formation of ring galaxies from a nonbarred target. Depending on the impact angle and position, the center of the bar may be temporarily offset from that of the disc.
In the second type of interactions the companion is initially in a near-circular orbit in a plane either coinciding with the plane of the target disc, or at a small angle to it. The merging destroys the bar. The disc expands both in the vertical and the radial direction so that its shape remains that of a thin disc. If the orbit is at an angle with the target disc the latter undergoes an important tilt.
