Scientific paper

Limber's (1965) tidal model for the interacting pair of galaxies VV 117 is improved based on the H I observations made by Gallagher et al. (1981). It is proposed that the spiral galaxy is being disrupted in a slightly overlapping encounter with the elliptical galaxy, which is about twice as massive as the spiral, in an elliptic orbit with eccentricity of roughly 0.3. A closer collision with a larger eccentricity would also be consistent with observations.
