Efficiency of Tidal Dissipation in Convective Flow Under Rapid Tidal Forcing
Hongzhe Zhou, Dong Lai
For close binaries and star-planet systems, tidal interactions mediate the energy transfer between the orbital motion and the internal flows of the bodies involved, thus playing a…
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…
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…
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…
Hierarchical Black Hole Mergers in Nuclear Star Clusters: A Combined Dynamical-Secular Channel for GW231123-like Events
Bin Liu, Dieran Wang, Dong Lai
The recent binary black hole (BH) merger GW231123, with both components likely in the high-mass gap and with high spins, challenges standard BH binary formation models. It is usual…
Resonance Capture of a Test Particle by an Eccentric Planet in the Presence of Externally-Driven Apsidal Precession
JT Laune, Dong Lai
Planets undergoing convergent migration can be captured into mean-motion resonance (MMR), in which the planets' periods are related by integer ratios. The dynamics of MMR are typic…
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…
Equation of State of Decompressed Quark Matter, and Observational Signatures of Quark-Star Mergers
Zhiqiang Miao, Zhenyu Zhu, Dong Lai
Quark stars are challenging to confirm or exclude observationally because they can have similar masses and radii as neutron stars. By performing the first calculation of the non-eq…
Progress report on the BEBOP search for circumbinary planets with radial velocities
Thomas A. Baycroft, Amaury H. M. J. Triaud, Dong Lai
The BEBOP (Binaries Escorted By Orbiting Planets) survey is a search for circumbinary planets using the radial velocity spectrographs HARPS and SOPHIE, currently focusing on single…
Migration of Accreting Planets and Black Holes in Disks
JT Laune, Rixin Li, Dong Lai
Nascent planets are thought to lose angular momentum (AM) to the gaseous protoplanetary disk via gravitational interactions, leading to inward migration. A similar migration proces…
Dynamical Friction Models for Black-Hole Binary Formation in AGN Disks
Kecheng Qian, Jiaru Li, Dong Lai
Stellar-mass black holes (sBH) embedded in gaseous disks of active galactic nuclei (AGN) can be important sources of detectable gravitational radiation for LIGO/Virgo when they for…
Formation of Merging Stellar-Mass Black Hole Binaries by Gravitational Wave Emission in Active Galactic Nucleus Disks
Barak Rom, Re'em Sari, Dong Lai
Many stellar-mass Black Holes (sBHs) are expected to orbit supermassive black holes at galactic centers. For galaxies with Active Galactic Nuclei (AGN), it is likely that the sBHs…
Apsidal Alignment and Anti-Alignment of Planets in Mean-Motion Resonance: Disk-Driven Migration and Eccentricity Driving
JT Laune, Laetitia Rodet, Dong Lai
Planets migrating in their natal discs can be captured into mean-motion resonance (MMR), in which the planets' periods are related by integer ratios. Recent observations indicate t…
Innermost Stable Circular Orbit of Inspiraling Neutron-Star Binaries: Tidal Effects, Post-Newtonian Effects and the Neutron-Star Equation of State
Dong Lai, Alan G. Wiseman
We study how the neutron-star equation of state affects the onset of the dynamical instability in the equations of motion for inspiraling neutron-star binaries near coalescence. A…
