Figure 1. Effect of the spin parameter on periastron precession for a binary with a symmetric mass ratio ν = 10−3. With a fixed spin parameter, an orbit with a bigger semilatus rectum has a smaller periastron precession. For an orbit with the same eccentricity and semilatus rectum, a larger spin parameter induces a smaller periastron precession.
