KELT-20b: A Giant Planet with a Period of P ∼ 3.5 days Transiting the V ∼ 7.6 Early A Star HD 185603
Abstract We report the discovery of KELT-20b, a hot Jupiter transiting a <?CDATA $V\sim 7.6$?> early A star, HD 185603, with an orbital period of <?CDATA $P\simeq 3.47$?> days. Archival and follow-up photometry, Gaia parallax, radial velocities, Doppler tomography, and AO imaging were used to confirm the planetary nature of …
