Abstract

K2-140b (EPIC 228735255b) is a weakly inflated hot Jupiter discovered by Giles et al. (2018). The discovery photometry was comprised of the K2 (Howell et al. 2014) long-cadence observations from Campaign 10b, which ran between 2016 July 13 and September 20, and of one partial-transit data set from 2017 March 18 obtained by the 1 m telescope of the Las Cumbres Observatory telescope network in South Africa (Brown et al. 2013). Their photometric data sets cover a baseline of 8.2 months, which led to the determination of the orbital period of ${6.569300}_{-0.000020}^{+0.000017}$ days with an epoch of BJD 2457588.28380 ± 0.00014 (Giles et al. 2018).
