The Illusory Precision of TTV Masses: Hidden Solutions Behind Kepler-9's Tight Mass Ratio
Sheng Jin, Dong-Hong Wu, Xiao-Ling Xu +1
Transit timing variations (TTV) are considered a tool for constraining the masses of transiting planets in the absence of radial-velocity data. Although theoretical studies have lo…

Nii-body: Bayesian Inference of Multiplanet Dynamics via N-body Simulations
Hong-Fei Jia, Sheng Jin, Dong-Hong Wu +1
Many exoplanetary systems are multiplanet configurations whose long-term dynamics are governed by N-body gravitational interactions. Consequently, their detection signatures cannot…

Eccentricity Evolution of Warm Jupiters: The Role of Distant Perturbers and Nearby Companions
Ying He, Dong-Hong Wu, Sheng Jin
Warm Jupiters-giant exoplanets with orbital periods between 10 and 200 days-exhibit a broad range of eccentricities and are often accompanied by nearby low-mass planets. Understand…
