On the Correlation between Hot Jupiters and Stellar Clustering: High-eccentricity Migration Induced by Stellar Flybys

no code implementations16 Feb 2021 Laetitia Rodet, Yubo Su, Dong Lai

A recent observational study suggests that the occurrence of hot Jupiters (HJs) around solar-type stars is correlated with stellar clustering.

Enhanced Lidov-Kozai migration and the formation of the transiting giant planet WD1856+534b

no code implementations8 Oct 2020 Christopher E. O'Connor, Bin Liu, Dong Lai

By requiring that perturbations from the companion stars be able to overcome short-range forces and excite the planet's eccentricity to $e \simeq 1$, we obtain an absolute limit of $a_{1} \gtrsim 8 \, {\rm AU} \, (a_{3} / 1500 \, {\rm AU})^{6/7}$ for the planet's semi-major axis just before migration (where $a_{3}$ is the semi-major axis of the 'outer' orbit).
