Modified gravity over the linearized metric perturbation for two body
  dynamics
  In this paper Modified gravity is studied over the linearized metric
perturbation in post-Minkowskian theory. This is a different aspect for two
body dynamics without taking usual self force originated from the radiative
backscattering of gravitational waves. The new multiplicative approach to
determine the background metric of curved space-time for two different massive
sources is computed in post-Newtonian theory. The theoretical result is checked
for galactic flat rotation curve and is very good agreement with solar
rotational speed.
