The spacetimes modified by the scalar field are explicitly given for the so-called gamma-metric and the Erez-Rosen metric with quadrupole moment q, and the influence of the additional deformation parameters gamma* and q* generated by the scalar field is studied. It is shown that the null energy condition is satisfied for the phantom field, but it is not satisfied for the standard scalar field. The test particle motion in both the modified gamma-metric and the Erez-Rosen quadrupole metric is studied; the circular geodesics are determined, and near-circular trajectories are explicitly presented for characteristic values of the spacetime parameters. It is also demonstrated that the parameters gamma* and q* have no influence on the test particle motion in the equatorial plane. ER -
