Quadrupole distortion of a mass with quadrupole — •Shokoufe Faraji — Bremen

In this paper the space-time of a mass with quadrupole in the presence of an external distribution of matter up to quadrupole is constructed. This space-time explains the exterior of a static and axially symmetric object locally, by its definition. The main goal of this work is to study this space-time and the effects of quadrupole moments via the geodesics motion, especially circular orbits on the equatorial plane. If the effects due to the rotation are negligible, this metric can describe the exterior of any axially symmetric astrophysical model up to quadrupole in a more realistic way in the sense that mostly astrophysical objects, are not isolated.
