Laplace surface of eccentric orbits around Kerr black hole and black-hole effects on Lidov-Kozai cycles

Abstract We study the Laplace surface of eccentric orbits around a Kerr black hole with a companion star. The two relativistic effects (periapsis apsidal precession and Lense-Thirring precession) balance companion’s tidal effect. By solving the secular equations, we find that the...
