A crucial aspect of understanding planet formation is determining the binarity of the host stars. Results from radial velocity (RV) 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 RV data are consistent with an orbiting star. We present a revised orbit …

We announce the discovery of a highly inflated transiting hot Jupiter by the KELT-North survey. A global analysis including constraints from isochrones indicates that the V = 10.8 host star (HD 343246) is a mildly evolved, G dwarf with {T}{eff}={5754}-55+54 K, {log} g={4.078}-0.054+0.049, [{Fe}/{{H}}]=0.272+/- 0.038, an inferred mass {M}*={1.211}-0.066+0.078 {M}☉ , and radius {R}*={1.67}-0.12+0.14 {R}☉ . The planetary companion has a mass {M}{{P}}={0.867}-0.061+0.065 MJ, radius {R}{{P}}={1.86}-0.16+0.18 RJ, surface gravity {log} {g} …

We report the discovery of KELT-7b, a transiting hot Jupiter with a mass of 1.28+/- 0.18 MJ, radius of {1.533}-0.047+0.046 RJ, and an orbital period of 2.7347749+/- 0.0000039 days. The bright host star (HD 33643; KELT-7) is an F-star with V = 8.54, Teff = 6789{}-49+50 K, [Fe/H] = {0.139}-0.081+0.075, and {log}\{\text{}}g\=4.149+/- 0.019. It has a mass of {1.535}-0.054+0.066 M☉, a radius of {1.732}-0.045+0.043 R☉, and is the fifth most massive, fifth hottest, and the ninth brightest star known to …
