  A crucial aspect of understanding planet formation is determining the
binarity of the host stars. Results from radial velocity surveys and the
follow-up of Kepler exoplanet candidates have demonstrated that stellar
binarity certainly does not exclude the presence of planets in stable orbits
and the configuration may in fact be relatively common. Here we present new
results for the 30 Arietis system which confirms that the B component hosts
both planetary and stellar companions. Keck AO imaging provides direct
detection of the stellar companion and additional radial velocity data are
consistent with an orbiting star. We present a revised orbit of the known
planet along with photometry during predicted transit times. Finally, we
provide constraints on the properties of the stellar companion based on orbital
stability considerations.
