Planet-Planet (P–P) scattering is a leading dynamical mechanism invoked to explain the present orbital distribution of exoplanets. Many stars belong to binary systems, therefore it is important to understand how this mechanism works in presence of a companion star. We focus on systems of three planets orbiting the primary star and estimate the timescale for instability finding that it scales with the keplerian period for systems that have the same ratio between inner planet and binary semi…

Planetary Population Synthesis

In stellar astrophysics, the technique of population synthesis has been successfully used for several decades. For planets, it is in contrast still a young method which only became important in

Planet formation in Binaries

Spurred by the discovery of more than 60 exoplanets in multiple systems, binaries have become in recent years one of the main topics in planet-formation research. Numerous studies have investigated

An efficient integrator that uses Gauss-Radau spacings

A self-starting integrator, RADAU proceeds by sequences within which the substeps are taken at Gauss-Radau spacings, which allows rather high orders of accuracy with relatively few function evaluations.
