abstract

Here, we derive the metric for the spacetime around rotating object for the gravity action having nonlocal correction of $R\Box^{-2} R $ to the Einstein-Hilbert action. Starting with the generic stationary, axisymmetric metric, we solve the equations of motion in linearized gravity limit for the modified action including energy-momentum tensor of the rotating mass. We also derive the rotating metric from the static metric using the Demanski-Janis-Newmann algorithm. Finally, we obtain the constraint on the value of $M$ by calculating the frame dragging effect in our theory and comparing it with that of General Relativity and Gravity Probe B results, where $M$ is the mass scale of the theory.

  • Geodetic Motion Around Rotating Blackhole in Nonlocal Gravity gr-qc · 2019-08-21 · reject · none · ref 5 · internal anchor

    For the RR model of nonlocal gravity, orbital frequency shifts around a Kerr-like black hole are reported, but the metric is imported from prior work and no reproducible calculation is provided.
