Аннотация:The gravitational field of a static, sphericallysymmetric source of mass M and scalar charge q isconsidered. It is shown that the metric expression forthis source is considerably simplified in two limiting cases: a) for M2 ≫ 4πq2/G,that is when the mass of the source is the maincontributor in the gravitational field; b) forq2 ≫ M2G/4π, when theenergy-momentum tensor of the static, spherically symmetric scalar field is the main contributorin the gravitational field. In the limiting caseq2 ≫ M2G/4π, the geodesicsof the massive and massless particles are studied. It isshown that gravitational forces of repulsion act on a particle movingnon-radially in this field. As a result, voids should becreated in the region surrounding such sources in theUniverse. Moreover, the stars with considerable scalar charge q2 ≫M2G/4π will act not as convexgravitational lenses as in the case whenq2≪ M2G/4π, but as concavegravitational lenses for the electromagnetic rays oflarge impact parameter.
