Polar orbit for Gliese 436 b

Bourrier et al. "Orbital misalignment of the Neptune-mass exoplanet GJ 436b with the spin of its cool star"

The orbit of GJ 436 b is nearly perpendicular to the stellar equator. This might be the result of Kozai oscillations, in which case some constraints can be put on the perturbing companion "GJ 436 c"
