Dynamical Excitation as a probe of planetary origins
Brad M. S. Hansen, Tze-Yeung Yu, Neel Nagarajan +1
We present a set of numerical simulations of the dynamical evolution of compact planetary systems migrating in a protoplanetary disk whose inner edge is sculpted by the interaction…

Widespread disruption of resonant chains during protoplanetary disk dispersal
Brad M. S. Hansen, Tze-Yeung Yu, Yasuhiro Hasegawa
We describe the evolution of low mass planets in a dispersing protoplanetary disk around a Solar mass star. The disk model is based on the results of Yu, Hansen & Hasegawa (2023),…

Predicting the Dominant Formation Mechanism of Multi-Planetary Systems
Cheyanne Shariat, Yasuhiro Hasegawa, Bradley M. S. Hansen +2
Most, if not all, sun-like stars host one or more planets, making multi-planetary systems commonplace in our galaxy. We utilize hundreds of multi-planet simulations to explore the…
