The abundance of short-period planetary systems with high orbital obliquities relative to the spin of their host stars is often taken as evidence that scattering processes play important roles in the formation and evolution of these systems. More recent studies have suggested that wide binary companions can tilt protoplanetary disks, inducing a high stellar obliquity that form through smooth processes like disk migration. DS Tuc Ab, a transiting planet with an 8.138 day period in the 40 Myr… Expand

Shrinking binary and planetary orbits by Kozai cycles with tidal friction

Planet formation in discs with inclined binary companions: can primordial spin-orbit misalignment be produced?
Many hot Jupiter (HJ) systems have been observed to have their stellar spin axis misaligned with the planet's orbital angular momentum axis. The origin of this spin-orbit misalignment and theExpand
A primordial origin for misalignments between stellar spin axes and planetary orbits
It is suggested that in the absence of strong coupling between the angular momentum of the disk and that of the host star, or of sufficient dissipation that acts to realign the stellar spin axis and the planetary orbits, the fraction of planetary systems whose angular momentum vectors will be commensurate with the rate of primordial stellar multiplicity.
