Planet-Driven Scatterings of Planetesimals Into a Star: Probability, Timescale and Applications
Laetitia Rodet, Dong Lai
A planetary system can undergo multiple episodes of intense dynamical activities throughout its life, resulting in the production of star-grazing planetesimals (or exocomets) and p…
On the pollution of white dwarfs by exo-Oort cloud comets
Christopher E. O'Connor, Dong Lai, Darryl Z. Seligman
A large fraction of white dwarfs (WDs) have metal-polluted atmospheres, which are produced by accreting material from remnant planetary systems. The composition of the accreted deb…
Giant planet engulfment by evolved giant stars: light curves, asteroseismology, and survivability
Christopher E. O'Connor, Lars Bildsten, Matteo Cantiello +1
About ten percent of Sun-like (-) stars will engulf a - planet as they expand during the red giant branch (RGB) or asymptotic giant branch (AGB) phas…
Eccentricity Growth of Massive Planets inside Cavities of Protoplanetary Discs
Marina M. Romanova, Alexander V. Koldoba, Galina V. Ustyugova +2
We carry out hydrodynamical simulations to study the eccentricity growth of a 1-30 Jupiter mass planet located inside the fixed cavity of a protoplanetary disc. The planet exchange…
Wide binary stars formed in the turbulent interstellar medium
Siyao Xu, Hsiang-Chih Hwang, Chris Hamilton +1
The ubiquitous interstellar turbulence regulates star formation and the scaling relations between the initial velocity differences and the initial separations of stars. We propose…
Hydrodynamical Evolution of Black-Hole Binaries Embedded in AGN Discs: III. The Effects of Viscosity
Rixin Li, Dong Lai
Stellar-mass binary black holes (BBHs) embedded in active galactic nucleus (AGN) discs offer a distinct dynamical channel to produce black hole mergers detected in gravitational wa…
