Efficiency of Tidal Dissipation in Convective Flow Under Rapid Tidal Forcing
Hongzhe Zhou, Dong Lai
The paper uses three‑dimensional simulations of a convective layer sandwiched between stable zones to measure how efficiently tidal energy is dissipated when the tidal forcing freq…
Hierarchical Black Hole Mergers in Nuclear Star Clusters: A Combined Dynamical-Secular Channel for GW231123-like Events
Bin Liu, Dieran Wang, Dong Lai
The paper proposes that hierarchical (second‑generation) black hole mergers like GW231123 can arise in nuclear star clusters through combined binary‑single interactions and secular…
A Formation Crisis of Repeating Partial Tidal Disruption Events
Zhen Pan, Dong Lai
A number of candidate repeating partial tidal disruption events (rpTDEs) have been reported in recent years. If these events are confirmed, the high fraction of observed rpTDEs amo…
Understanding the UV/Optical Variability of AGNs through Quasi-Periodic Large-scale Magnetic Dynamos
Hongzhe Zhou, Dong Lai
The physical origin of the recently identified slow-moving temperature fluctuations in accretion disks around super-massive black holes (SMBHs) cannot be accounted for by reverbera…
Velocities of Free Floaters in a Sea of Stars
Jun Yan Lau, Dong Lai
We investigate the velocity evolution of free-floating planets and interstellar objects (``free floaters'') through gravitational scatterings by field stars (with the stellar mass…
Simulations of a Conducting Sphere Moving through Magnetized Plasma: Alfvén Wings, Slow Magnetosonic Wings, and Drag Force
Nicholas Corso, Dong Lai
Plasma-mediated interaction between astrophysical objects can play an important role and produce electromagnetic radiation in various binary systems, ranging from planet-moon and s…
