MEASURING THE SPIN OF THE PRIMARY BLACK HOLE IN OJ287
The compact binary system in OJ287 is modeled to contain a spinning primary black hole with an accretion disk and a non-spinning secondary black hole. Using post-Newtonian (PN) accurate equations that include 2.5PN accurate non-spinning contributions, the leading-order general relativistic and classical spin–orbit terms, the orbit of the binary black …
