Analytical Solutions for Planet-Scattering Small Bodies
Yukun Huang, Brett Gladman, Eiichiro Kokubo
Gravitational scattering of small bodies (planetesimals) by a planet remains a fundamental problem in celestial mechanics. It is traditionally modeled within the circular restricte…
The Detectability of Lunar-Origin Asteroids in the LSST Era
Yixuan Wu, Yifei Jiao, Wen-Yue Dai +5
While most near-Earth asteroids (NEAs) are thought to originate from the main belt, recent discoveries have suggested the existence of a lunar-derived NEA population, such as the a…
Early Stellar Flybys are Unlikely: Improved Constraints from Sednoids and Large- TNOs
Qingru Hu, Yukun Huang, Brett Gladman +1
Sedna-like objects (a.k.a. sednoids) are transneptunian objects (TNOs) characterized by large semimajor axes and exceptionally high perihelia. Their high- orbits are detached fr…
Dynamics of Binary Planets within Star Clusters
Yukun Huang, Wei Zhu, Eiichiro Kokubo
We develop analytical tools and perform three-body simulations to investigate the orbital evolution and dynamical stability of binary planets within star clusters. Our analytical r…
