Collisional dynamics in the field: Ultra-wide systems as sources for binary exotica (GW sources, sGRBs, Type Ia SN, X-ray source ...)
TYPEAstrophysics Seminar

Time:14:30 - 15:30
Location:Lidow 620
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
