Dynamics not foreseen?
That gives >10x too many hot Jupiters (Ida talk)

Disruption possible (Et>Eb) for
Maximum tidal input:
Planet binding energy:
work in progress with Doug Lin & Tsevi Mazeh
Lower mass planets
less binding energy
overflow more back away from the star further
Inclination to stellar equator?
