Target RA (J2000): 97.408173 and deg Target Dec (J2000): -21.99433 and deg Gaia GMag: 11.14 Programme ID: CH_PR140066 Programme Manager: NASCIMBENI PI of observing programme: Benz Title of programme: Axis 1 - Uncovering a maverick population: CHEOPS observations of hot Jupiter systems with inner small companions (MAVERICK) Abstract: Planetary systems hosting a hot or warm Jupiter (HJ/WJ) plus nearby small companion(s) such as WASP-47 (Nascimbeni et al. 2023) are extremely rare and very valuable to constrain formation and migration models. Only five such systems are known so far. Our goal is to increase the sample size by confirming and characterizing five TESS candidates with such an architecture and improving their orbital/physical parameters including ephemeris radii and (when feasible) planetary masses through TTVs. As demonstrated by our work on WASP-47 RVs and TTVs are very synergistic at decoding these complex systems. A dedicated RV follow-up will be coordinated. [truncated!

目标赤经（J2000坐标系）：97.408173度 目标赤纬（J2000坐标系）：-21.99433度 盖亚G星等：11.14 项目编号：CH_PR140066 项目主管：NASCIMBENI 观测项目首席研究员：Benz 项目标题：Axis 1——揭示特立独行的群体：CHEOPS卫星对拥有内部小伴星的热木星系统的观测（MAVERICK） 摘要：拥有热木星或暖木星（HJ/WJ）及邻近小伴星的行星系统（如WASP-47，Nascimbeni等人，2023）极为罕见，对约束形成与迁移模型具有重要价值。目前已知的此类系统仅五个。我们的目标是通过确认并表征五个具有该架构的TESS候选体，同时通过凌星时间变化（Transit Timing Variations，TTVs）改进其轨道/物理参数（包括星历半径及可行时的行星质量），以扩大样本规模。正如我们在WASP-47研究中所展示的，视向速度（Radial Velocities，RVs）与凌星时间变化（TTVs）在解析这些复杂系统时具有极强的协同作用。我们将协调开展专门的视向速度后续观测。[内容截断！请查阅实际数据获取全文]
