Abstract:

The secular evolution of hierarchical triple systems plays an important role in many astrophysical enviroments，from the planet-moon systems to the massive black hole binaries at the center of galaxies. If the mutual inclination angle between the inner and outer orbits is sufficiently high，there exists large amplitude oscillations in the orbital eccentricity and inclination of the inner binaries, which is so called Lidov-Kozai oscillation.
In this talk, I will discuss our recent works on the secular evolution of the hierarchical triple systems with black holes.
