Spin and Obliquity Distributions of Low-mass Planets Shaped by Dynamical Instability
Dieran Wang, Jiaru Li, Dong Lai
Exoplanetary systems hosting multiple low-mass planets are thought to have experienced dynamical instability, during which planet-planet collisions and mergers occur; these collisi…

Magnetically Driven Retrograde Precession in Misaligned Black Hole Accretion Flows
Hong-Xuan Jiang, Yosuke Mizuno, Dong Lai +2
Observations of accreting black hole (BH) systems, such as microquasars and supermassive black holes, often reveal a precessing jet with changing directions, indicating a misaligne…

Binary Stars Approaching Supermassive Black Holes: Hydrodynamics of Stellar Collisions, Mass Fallback and Partial TDEs
Fangyuan Yu, Dong Lai
When binaries are injected into low-angular-momentum orbits around a central supermassive black hole (SMBH), various outcomes can occur, including binary tidal breakup, double stel…
