Extrasolar Planetary Systems

One of the mysteries arising from the study of exoplanets is that we see systems where the planets are misaligned, even though they are born in a flat, circular disk. Maybe a cosmic tsunami hit these systems and rearranged everything about them, but we haven’t had proof. Our paper gives rare observational evidence for one of these flybys gently influencing one of the planetary systems in the galaxy.
