A systematic study about orbit flips of test particles caused by eccentric von Zeipel-Lidov-Kozai effects
Hanlun Lei
The problem of orbit flips caused by eccentric von Zeipel-Lidov-Kozai effects is systematically investigated by means of three approaches, including Poincaré sections, dynamical sy…
Structures of secular resonances for inner test particles in hierarchical planetary systems
Hanlun Lei
In this study, dynamics of secular resonances for inner test particles are investigated under the octupole-level approximation by taking non-perturbative approaches. In practice, w…
Apsidal asymmetric-alignment of Jupiter Trojans
Jian Li, Hanlun Lei, Zhihong J. Xia
The most distant Kuiper belt objects exhibit the clustering in their orbits, and this anomalous architecture could be caused by Planet 9 with large eccentricity and high inclinatio…
Secular resonance of inner test particles in hierarchical planetary systems
Hanlun Lei
The present work studies the secular resonance associated with the critical argument ( is the longitude of pericentre) for inner test particles moving in low-ec…
Dynamical structures of retrograde resonances: analytical and numerical studies
Hanlun Lei, Jian Li
In this work, retrograde mean motion resonances (MMRs) are investigated by means of analytical and numerical approaches. Initially, we define a new resonant angle to describe the r…
Multi-harmonic Hamiltonian models with applications to first-order resonances
Hanlun Lei, Jian Li
In this work, two multi-harmonic Hamiltonian models for mean motion resonances are formulated and their applications to first-order resonances are discussed. For the : reso…
