Scientific paper

The observations of triple galaxies are simulated numerically to obtain a proper way to use the virial theorem for mass estimations. The results are applied to the triple galaxies cataloged by Karachentsev (1987). The dynamics is simulated using both the point-mass model and softened potential models. The results indicate that significant deviation from the point-mass model requires that the typical intergalactic distances are comparable to the half-mass radii of the galaxies. Such physical conditions would lead to rapid mergers of the galaxies. Thus, the existence of the observed triplets suggests that they are at sufficient distances from each other to justify the use of the point-mass model at least for their present dynamical state. The mass estimates obtained for the Karachentsev triplets have almost an order of magnitude excess compared to the visible mass, when a standard mass-to-light ratio is assumed.
