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…
Halting Migration in Magnetospherically Sculpted Protoplanetary Disks
Tze Yeung Mathew Yu, Brad Hansen, Yasuhiro Hasegawa
We present a physically motivated model for the manner in which a stellar magnetic field sculpts the inner edge of a protoplanetary disk, and examine the consequence for the migrat…
Close-in giant-planet formation via in-situ gas accretion and their natal disk properties
Yasuhiro Hasegawa, Tze Yeung Mathew Yu, Bradley M. S. Hansen
The origin of close-in Jovian planets is still elusive. We examine the in-situ gas accretion scenario as a formation mechanism of these planets. We reconstruct natal disk propertie…
Trans-Neptunian Objects Transiently Stuck in Neptune's Mean Motion Resonances: Numerical simulations of the current population
Tze Yeung Mathew Yu, Ruth Murray-Clay, Kathryn Volk
A substantial fraction of our solar system's trans-Neptunian objects (TNOs) are in mean motion resonance with Neptune. Many of these objects were likely caught into resonances by p…
OSSOS IX: two objects in Neptune's 9:1 resonance -- implications for resonance sticking in the scattering population
Kathryn Volk, Ruth A. Murray-Clay, Brett J. Gladman +12
We discuss the detection in the Outer Solar System Origins Survey (OSSOS) of two objects in Neptune's distant 9:1 mean motion resonance at semimajor axis ~au. Both ob…
