Three body systems: triples amp binary single

Triple systems are among the most frequent astrophysical phenomena manifesting themselves in almost any given scale where triple stars planets in binaries and even our own Sun Earth moon system serve as a few obvious examples I will show the implication of three body interaction on several astrophysical systems: triple stellar system Pluto Charon system and low mass X ray sources If time permits I will present some preliminary results exoplanets and constraining CE timescale through three body interaction
