Princeton University Extrasolar Planet Discussion Group

Magnetic field and tide are of importance for celestial bodies. In the first part, I will discuss uniform rotation of solar radiative zone, convection dynamo in star, precession dynamo in planet, and collision dynamo in planetesimal. In the second part, I will discuss tidal inflation of hot Jupiter, tidal wave resonance with orbital motion, tidal wave transmission, and magnetic effect on tidal dissipation. Then I will discuss the condition where to find exomoons, and finally the disk instability due to self-gravity to interpret high-mass planet formation.
