Account of a Dark Energy Model in the Roche Potential for Interacting Galaxies

Abstract

The influence of a dark energy model – a new nonvacuum field – has been considered here for the first time in the generalized Roche potential with the equivalence principle taken into account for interacting galaxies. An equation of the thermodynamics of the indicated field is derived and its possible evolutions, influencing the accelerated expansion of the Universe, are discussed.
