Data-driven discovery of non-Newtonian astronomy via learning non-Euclidean Hamiltonian
Oswin So, Gongjie Li, Evangelos A. Theodorou +1
Incorporating the Hamiltonian structure of physical dynamics into deep learning models provides a powerful way to improve the interpretability and prediction accuracy. While previo…
Mutual Inclination of Ultra-Short-Period Planets with Time Varying Stellar J2-moment
Chen Chen, Gongjie Li, Cristobal Petrovich
Systems with ultra-short-period planets (USPs) tend to possess larger mutual inclinations compared to those with planets located farther from their host stars. This could be explai…
Exomoons in Systems with a Strong Perturber: Applications to Cen AB
Billy Quarles, Siegfried Eggl, Marialis Rosario-Franco +1
The presence of a stellar companion can place constraints on occurrence and orbital evolution of satellites orbiting exoplanets, i.e., exomoons. In this work we revise earlier orbi…
Tilting Planets During Planet Scattering
Gongjie Li
Observational constraints on planet spin-axis has recently become possible, and revealed a system that favors a large spin-axis misalignment, a low stellar spin-orbit misalignment…
GRIT: a package for structure-preserving simulations of gravitationally interacting rigid-bodies
Renyi Chen, Gongjie Li, Molei Tao
Spin-orbit coupling of planetary systems plays an important role in the dynamics and habitability of planets. However, symplectic integrators that can accurately simulate not only…
Application of Orbital Stability and Tidal Migration Constraints for Exomoon Candidates
Billy Quarles, Gongjie Li, Marialis Rosario-Franco
Satellites of extrasolar planets, or exomoons, are on the frontier of detectability using current technologies and theoretical constraints should be considered in their search. In…
