我们提出了三个新的过境巨行星的发现，首次发现的WASP望远镜，并建立其行星性质与后续的光谱学和地面测光光变曲线。WASP-92是一颗F7星星，有一颗中等膨胀的行星，其轨道周期为2.17天，Rp = 1.461 ± 0.077 RJ，Mp = 0.805 ± 0.068 MJ。WASP-93 b每2.73天绕它的F4宿主星星一周，Rp = 1.597 ± 0.077 RJ，Mp = 1.47 ± 0.029 MJ。WASP-118 b也有一颗热的宿主星星（F6），并且适度膨胀，其中Rp = 1.440 ± 0.036 RJ，Mp = 0.513 ± 0.041 MJ，行星的轨道周期为4.05天。它们是明亮的目标（V = 13.18，10.97和11.07），非常适合进一步的表征工作，特别是WASP-118 b，它是K2作为活动8的一部分进行观测的。WASP-93 b预计将潮汐向外迁移，这与大多数发现的热彗星的潮汐行为不同。
We present the discovery of three new transiting giant planets, first detected with the WASP telescopes, and establish their planetary nature with follow up spectroscopy and ground-based photometric lightcurves. WASP-92 is an F7 star, with a moderately inflated planet orbiting with a period of 2.17 days, which has Rp = 1.461 ± 0.077RJ and Mp = 0.805 ± 0.068MJ. WASP-93b orbits its F4 host star every 2.73 days and has Rp = 1.597 ± 0.077RJ and Mp = 1.47 ± 0.029MJ. WASP-118b also has a hot host star (F6) and is moderately inflated, where Rp = 1.440 ± 0.036RJ and Mp = 0.513 ± 0.041MJ and the planet has an orbital period of 4.05 days. They are bright targets (V = 13.18, 10.97 and 11.07 respectively) ideal for further characterisation work, particularly WASP-118b, which is being observed by K2 as part of campaign 8. WASP-93b is expected to be tidally migrating outwards, which is divergent from the tidal behaviour of the majority of hot Jupiters discovered.
