The HIRES science case
... In general planets were thought to be mostly on orbits coplanar with their star's equator, something in line with predictions of disc migration. Recent results have shown that hot Jupiter planets on non-coplanar orbits are common, including some planets on retrograde orbits (Triaud et al. 2010). Tho ...
