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…
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…
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…
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…
