How do External Companions Affect Spin-Orbit Misalignment of Hot Jupiters?
Dong Lai, Kassandra R. Anderson, Bonan Pu
Consider a planet with its orbital angular momentum axis aligned with the spin axis of its host star. To what extent does an inclined distant companion (giant planet or binary star…
Chaotic quadruple secular evolution and the production of misaligned exomoons and Warm Jupiters in stellar multiples
Evgeni Grishin, Dong Lai, Hagai B. Perets
We study the chaotic and secular evolution of hierarchical quadruple systems in the configuration, focusing on the evolution of mutual inclination of the inner binaries as th…
Resonant Tidal Excitation of Oscillation Modes in Merging Binary Neutron Stars: Inertial-Gravity Modes
Wenrui Xu, Dong Lai
In coalescing neutron star (NS) binaries, tidal force can resonantly excite low-frequency (< 500 Hz) oscillation modes in the NS, transferring energy between the orbit and the NS.…
Trapping of Low-Mass Planets Outside the Truncated Inner Edges of Protoplanetary Discs
Ryan Miranda, Dong Lai
We investigate the migration of a low-mass () planet near the inner edge of a protoplanetary disc using two-dimensional viscous hydrodynamics simulations. We…
Secular chaotic dynamics in hierarchical quadruple systems, with applications to hot Jupiters in stellar binaries and triples
Adrian S. Hamers, Dong Lai
Hierarchical quadruple systems arise naturally in stellar binaries and triples that harbour planets. Examples are hot Jupiters (HJs) in stellar triple systems, and planetary compan…
Inclination Evolution of Protoplanetary Disks Around Eccentric Binaries
J. J. Zanazzi, Dong Lai
It is usually thought that viscous torque works to align a circumbinary disk with the binary's orbital plane. However, recent numerical simulations suggest that the disk may evolve…
