Resonant Super-Earths Dancing With EKL Oscillations: TTV Phase Excitation and Resonance Disruption by EKL Interactions between a Cold Jupiter and Stellar Companion

Pin-Gao Gu, Gongjie Li

Near-resonant Kepler planets are dynamically hot, as evidenced by nonzero transit timing variation (TTV) phases, indicating that free eccentricities are not damped. Recent observat…

Solving Inverse Problems of Chaotic Systems with Bidirectional Conditional Flow Matching

Peiyan Hu, Jian Zhang, Jiashu Pan +6

Modeling chaotic systems is crucial yet challenging. Inverse problems in chaotic dynamics, namely inferring initial conditions from final states, remain largely unsolved because of…

Observational and Dynamical Constraints on an Unseen Outer Perturber in the GJ 436 Hot Neptune System

Haedam Im, Tiger Lu, Malena Rice +3

Hot Neptunes in the sub-Jovian desert offer unique insights into planetary system evolution, retaining signatures of dynamical processes that shaped their present-day architectures…

Unified Formation Channel of Hot and Warm Jupiters via Planet-Planet Scattering

Julia Esposito, Gongjie Li, Songhu Wang

Recent observations show distinct orbital architectures for hot and warm Jupiters: hot Jupiters span a wide range of stellar obliquities and tend to host distant companions without…

Peekaboo: Secular Resonances from Evolving Stellar Oblateness Impede Transit Detection

Thea Faridani, Smadar Naoz, Gongjie Li +2

Secular resonances in exoplanet systems occur when two or more planets have commensurabilities in the precession rates of their orbital elements, causing an exchange of angular mom…

The Dynamical History of HIP-41378 f -- Oblique Exorings Masquerading as a Puffy Planet

Tiger Lu, Gongjie Li, Ben Cassese +1

The super-puff HIP-41378 f represents a fascinating puzzle due to its anomalously low density on a far-out orbit in contrast with other known super-puffs. In this work, we explore…

More Likely Than You Think: Inclination-Driving Secular Resonances are Common in Known Exoplanet Systems

Thea Faridani, Smadar Naoz, Gongjie Li +2

Multi-planet systems face significant challenges to detection. For example, further orbiting planets have reduced signal-to-noise ratio in radial velocity detection methods, and sm…

Planet-Planet Scattering and ZLK Migration -- The Dynamical History of HAT-P-11

Tiger Lu, Qier An, Gongjie Li +4

The two planets of the HAT-P-11 system represent fascinating dynamical puzzles due to their significant eccentricities and orbital misalignments. In particular, HAT-P-11 b is on a…

Significant mutual inclinations between the stellar spin and the orbits of both planets in the HAT-P-11 system

Qier An, Tiger Lu, G. Mirek Brandt +2

Planet-star obliquity and planet-planet ]mutual inclination encode a planetary system's dynamical history, but both of their values are hard to measure for misaligned systems with…
