On the tidal evolution of Hot Jupiters on inclined orbits
Tidal friction is thought to be important in determining the long–term spin–orbit evolution of short–period extrasolar planetary systems. Using a simple model of the orbit–averaged effects of tidal friction (Eggleton et al. 1998), we study the evolution of close–in planets on inclined orbits, due to tides. We analyse the effects of the inclusion of stellar magnetic braking by performing a phase...

متن کاملObliquity Tides on Hot Jupiters
Obliquity tides are a potentially important source of heat for extrasolar planets on close-in orbits. Although tidal dissipation will usually reduce the obliquity to zero, a nonzero obliquity can persist if the planet is in a Cassini state, a resonance between spin precession and orbital precession. Obliquity tides might be the cause of the anomalously large size of the transiting planet HD 209...
متن کاملTwo Classes of Hot Jupiters
We identify two classes of transiting planet, based on their equilibrium temperatures and Safronov numbers. We examine various possible explanations for the dichotomy. It may reflect the influence of planet or planetesimal scattering in determining when planetary migration stops. Another possibility is that some planets lose more mass to evaporation than others. If this evaporation process pref...
متن کاملAtmospheric escape from hot Jupiters
The extra-solar planet HD209458b has been found to have an extended atmosphere of escaping atomic hydrogen (Vidal-Madjar et al. 2003), suggesting that “hot Jupiters” closer to their parent stars could evaporate. Here we estimate the atmospheric escape (so called evaporation rate) from hot Jupiters and their corresponding life time against evaporation. The calculated evaporation rate of HD209458...
