Resonant Excitation of Planetary Eccentricity due to a Dispersing Eccentric Protoplanetary Disk: A New Mechanism of Generating Large Planetary Eccentricities
Jiaru Li, Dong Lai
We present a new mechanism of generating large planetary eccentricities. This mechanism applies to planets within the inner cavities of their companion protoplanetary disks. A mass…
Ring Formation in Protoplanetary Disks Driven by an Eccentric Instability
Jiaru Li, Adam M. Dempsey, Hui Li +1
We find that, under certain conditions, protoplanetary disks may spontaneously generate multiple, concentric gas rings without an embedded planet through an eccentric cooling insta…
Orbital evolution of binary black holes in active galactic nucleus disks: a disk channel for binary black hole mergers?
Ya-Ping Li, Adam M. Dempsey, Shengtai Li +2
We perform a series of high-resolution 2D hydrodynamical simulations of equal-mass binary black holes (BBHs) embedded in active galactic nucleus (AGN) accretion disks to study whet…
Giant Planet Scatterings and Collisions: Hydrodynamics, Merger-Ejection Branching Ratio, and Properties of the Remnants
Jiaru Li, Dong Lai, Kassandra R. Anderson +1
Planetary systems with sufficiently small orbital spacings can experience planetary mergers and ejections. The branching ratio of mergers vs ejections depends sensitively on the tr…
Planetary Spin and Obliquity from Mergers
Jiaru Li, Dong Lai
In planetary systems with sufficiently small inter-planet spacing, close encounters can lead to planetary collisions/mergers or ejections. We study the spin property of the merger…
