Several hundred hot Jupiters are now known to orbit very close to their host star, where tidal effects are expected to have a significant impact on the planet's evolution. We search for evidence of tidal effects in the sample of known transiting planets by analysing new radial velocity measurements using the HARPS and SOPHIE spectrographs, as well as re-analysing existing radial velocity measurements and photometric constraints on the orbital elements from the literature.
We show that the orbital eccentricities and the projected spin-orbit alignment angles as measured from the Rossiter McLaughlin effect for known transiting planets, where available, are in fact fully compatible with classical tidal theory, without having recourse to special scenarios such as eccentricity pumping from a second companion in the system, etc. We also show that planets on circular orbits gather in a well-defined region in the mass-period plane at the shortest possible period for a given mass, and we reexamine the recent hypothesis that the presence of a convective stellar envelope leads to a spin-orbit alignment.
