Abstract: | The field of galaxies is widely regarded as a collisionless system. However, this is not the case for ultra-wide systems (binaries and triples). In this talk I will present a dynamical scenario in which ultra-wide systems are perturbed by random stellar encounters and as a result are driving to sufficiently high eccentricities and evolve to a variety of binary exotica |
