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…
In-Situ Scattering of Warm Jupiters and Implications for Dynamical Histories
Kassandra R. Anderson, Dong Lai, Bonan Pu
Many warm Jupiters (WJs) have substantial eccentricities, which are linked to their formation and migration histories. This paper explores eccentricity excitation of WJs due to pla…
Low-Eccentricity Migration of Ultra-Short Period Planets in Multi-Planet Systems
Bonan Pu, Dong Lai
Recent studies suggest that ultra-short period planets (USPs), Earth-sized planets with sub-day periods, constitute a statistically distinct sub-sample of {\it Kepler} planets: USP…
How do External Companions Affect Spin-Orbit Misalignment of Hot Jupiters?
Dong Lai, Kassandra R. Anderson, Bonan Pu
Consider a planet with its orbital angular momentum axis aligned with the spin axis of its host star. To what extent does an inclined distant companion (giant planet or binary star…
Ohmic Dissipation in Mini-Neptunes
Bonan Pu, Diana Valencia
In the presence of a magnetic field and weakly ionizing winds, ohmic dissipation is expected to take place in the envelopes of Jovian and lower-mass planets alike. While the proces…
Spacing of Kepler Planets: Sculpting by Dynamical Instability
Bonan Pu, Yanqin Wu
We study the orbital architecture of multi-planet systems detected by the Kepler transit mission using N-body simulations, focusing on the orbital spacing between adjacent planets…
