Stellar velocity perturbations in colliding galaxies. I
Abstract
Expressions for the stellar velocity perturbations in colliding galaxies, valid for any distance of closest approach, are derived analytically under the impulsive approximation for spherical galaxies using a Newtonian potential with a softening parameter. The results are compared with those of earlier workers.
