摘要
在本文中，我们报告发现一颗新的热木星 EPIC211089792 b，最初由 Super-WASP 天文台探测到，随后由 K2 空间任务在其第 4 次观测活动期间探测到。该行星周期为 3.25 d，质量为 0.73 ± 0.04 Mjup，半径为 1.19 ± 0.02 Rjup。宿主恒星是一颗相对明亮（V=12.5）的 G7 矮星，伴有一颗邻近的 K5V 伴星。基于恒星自转和锂丰度，我们发现该系统可能年轻至约 450 Myr。Rossiter-McLaughlin 效应的观测表明，该行星相对于恒星自转是对齐的。鉴于凌星深度（20 mmag）、恒星星等以及存在邻近恒星伴星，该行星是空间和地基透射光谱观测的良好目标，特别是在两颗恒星均相对明亮的近红外波段。
