abstract:
Extrasolar planets have been discovered in binary star systems orbiting around one of the stars in a circumstellar orbit or around the binary in a circumbinary orbit. For two of the tightest binaries with circumstellar planets, HD 59686 and nu Octantis, dynamical fitting of the radial velocity data and stability analysis show that the planets are most likely on retrograde orbits. In our own Solar System, there is also a remarkable system of four small satellites orbiting around the Pluto-Charon binary. In this talk, I will discuss the dynamics of these systems and the constraints that they place on the formation and evolution of planetary and satellite systems.
