Where Do Hot Jupiters Come From? Revisiting Tidal Disruption and Ejection in High-Eccentricity Migration

Qianli Fan, Shang-Fei Liu

Planets with dense cores avoid total tidal disruption in close encounters, allowing more to survive as hot Jupiters or stripped remnants.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

no total disruptions occur within the previously suggested destruction zone (≲ 2.7 rt). For deep encounters (≲ 1.7 rt) planets suffer severe envelope stripping and are either progressively downsized to dense remnants or ejected after a few close encounters.

C2weakest assumption

The hydrodynamic simulations with 10-20 Earth-mass cores accurately capture the envelope stripping and orbital energy changes without unmodeled effects like magnetic fields or realistic equation of state variations that could alter outcomes.

C3one line summary

Planets with realistic dense cores survive close star encounters without total disruption, allowing more to circularize into hot Jupiters or be ejected after mass loss.
