Some astrophysical consequences of the Jordan-Brans-Dicke theory

  • 11 Accesses

Abstract

It is shown that the appearance of a new dimensional constant — the speed of light — in the field equations of the Jordan-Brans-Dicke theory (JBD) makes it possible to construct from the set of constant constructions appearing in the system two with the dimension of energy. This is an indication of the existence of two branches of equilibrium configurations in the JBD theory, which was discovered from numerical calculations by Saakyan and Mnatsakanyan. The problem of the gravitational stability of the cosmological model of the JBD theory is considered. It is shown that the two modes of perturbation evolution obtained differ little from the perturbation modes in the Friedmann model.
