Abstract

We report the discovery of KELT-3b, a moderately inflated transiting hot Jupiter with a mass of 1.477_?0.067^+0.066 M_J, radius of 1.345 ± 0.072R_J, and an orbital period of 2.7033904 ± 0.000010 days. The host star, KELT-3, is a V = 9.8 late F star with M_* = 1.278^+0.063_?0.061M_⊙, R_* = 1.472^+0.065_?0.067 R _*, T_eff = 6306⁺⁵⁰_?49 K, log(g) = 4.209^+0.033_?0.031, and [Fe/H] = 0.044 ^+0.080_?0.082, and has a likely proper motion companion. KELT-3b is the third transiting exoplanet discovered by the KELT survey, and is orbiting one of the 20 brightest known transiting planet host stars, making it a promising candidate for detailed characterization studies. Although we infer that KELT-3 is significantly evolved, a preliminary analysis of the stellar and orbital evolution of the system suggests that the planet has likely always received a level of incident flux above the empirically identified threshold for radius inflation suggested by Demory and Seager.
