KELT-12b: A<i>P</i>∼ 5 day, Highly Inflated Hot Jupiter Transiting a Mildly Evolved Hot Star
We report the discovery of KELT-12b, a highly inflated Jupiter-mass planet transiting a mildly evolved host star. We identified the initial transit signal in the KELT-North survey data and established the planetary nature of the companion through precise follow-up photometry, high-resolution spectroscopy, precise radial velocity measurements, and high-resolution adaptive optics …
