“…There have been some works [Soares, 1996] with a semi-analytical description of the dynamics of two point galaxies san1,san2,bleh1,bitre,ezo but as far as we know, there have been few attempts to consider the mass variation problem in binary galaxies [Jeans, 1924, Jeans, 1928. The analytical treatment of two interacting galaxies as a two-body problem cannot be considered satisfactorily since one needs to consider the dynamics of binary galaxies with mass loss or mass exchange between them.…”
