Obliquity Tides on Hot Jupiters
نویسندگان
چکیده
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 209458b.

Cassini States with Dissipation: Why Obliquity Tides Cannot Inflate Hot Jupiters
Some short-period exoplanets (“hot Jupiters”) are observed by their transits to have anomalously large radii. It has been suggested that these planets are in a resonance involving persistent misalignment and synchronous precession of their spin and orbital angular momenta—a Cassini state—and that the attendant tidal heating inflates the planet. We argue against this. Using explicit tidal integr...
متن کاملThermal Tides in Short Period Exoplanets
Time-dependent insolation in a planetary atmosphere induces a mass quadrupole upon which the stellar tidal acceleration can exert a force. This “thermal tide” force can give rise to secular torques on the planet and orbit as well as radial forces causing eccentricity evolution. We apply this idea to the close-in gas giant exoplanets (“hot Jupiters”). The response of radiative atmospheres is com...
متن کاملConcerning thermal tides on hot Jupiters
By analogy with a mechanism proposed by Gold and Soter to explain the retrograde rotation of Venus, Arras and Socrates suggest that thermal tides may excite hot jovian exoplanets into nonsynchronous rotation, and perhaps also noncircular orbits. It is shown here that because of the absence of a solid surface above the convective core of a jovian planet, the coupling of the gravitational and the...
متن کاملHot Stars with Hot Jupiters Have High Obliquities
We show that stars with transiting planets for which the stellar obliquity is large are preferentially hot (Teff > 6250 K). This could explain why small obliquities were observed in the earliest measurements, which focused on relatively cool stars drawn from Doppler surveys, as opposed to hotter stars that emerged later from transit surveys. The observed trend could be due to differences in pla...
متن کاملObservational Consequences of Hydrodynamic Flows on Hot Jupiters
We use a grid-based shallow water model to simulate the atmospheric dynamics of the transiting hot Jupiter HD 209458b. Under the usual assumption that the planet is in synchronous rotation with zero obliquity, a steady state is reached with a well-localized cold spot centered 76◦ east of the antistellar point. This represents a departure from predictions made by previous simulations in the lite...
