Motion of massive particles in a static spherically symmetric metric in the scalar-tensor gravitation theory

The effect of a scalar charge on the trajectory of motion of massive particles in the case of a spherically symmetric model has been studied. The action of the gravitational field of a scalar star on the displacement of the trajectory pericenter of massive bodies has been demonstrated, as well as the agreement of the given theory with the predictions of the general relativity theory in the absence of a scalar source within the limits of the solar system.
