Stability of a cluster-disrupted mean-motion resonance (chain) in HR 8799 and PDS 70
Brent Maas, Shuo Huang, Simon Portegies Zwart
HR~8799 is a planetary system with four planets potentially in a mean-motion resonance chain. It is unclear from the observations if they are in mean-motion resonance. Similarly, P…
Oort Cloud Ecology. III. The Sun left the parent star cluster shortly after the giant planets formed
Simon Portegies Zwart, Shuo Huang
The Sun was born in a clustered environment with 10,000 other stars. Being an isolated star today, the Sun must have left the nest. We do not directly know when that happened, how…
The Dynamical History of the Kepler-221 Planet System
Tian Yi, Chris W. Ormel, Shuo Huang +1
Kepler-221 is a G-type star hosting four planets. In this system, planets b, c, and e are in (or near) a 6:3:1 three-body resonance even though the planets' period ratios show sign…
On the origin of transition disk cavities: Pebble-accreting protoplanets vs Super-Jupiters
Shuo Huang, Nienke van der Marel, Simon Portegies Zwart
Protoplanetary disks surrounding young stars are the birth places of planets. Among them, transition disks with inner dust cavities of tens of au are sometimes suggested to host ma…
