本文基于WASP巡天候选体并结合TESS空间测光、地面测光与光谱及视向速度数据,对9颗围绕FGK恒星的热木星进行了联合性质分析,更新了其半径、质量和轨道周期等参数。
摘要:
广角行星搜索(WASP)巡天提供了首批凌星热木星候选体中的一部分。随着凌星系外行星勘测卫星(TESS)的加入,许多WASP行星候选体现在已被重新审视,并获得了更新的凌星参数。在此,我们呈现9颗围绕FGK型恒星运行、由WASP巡天识别为候选体并通过视向速度测量确定行星质量的凌星行星。随后利用TESS获取的空间测光数据以及地面测光和光谱测量,对WASP-102 b、WASP-116 b、WASP-149 b、WASP-154 b、WASP-155 b、WASP-188 b、WASP-194 b/HAT-P-71 b、WASP-195 b和WASP-197 b的行星性质进行了联合分析。这些行星的半径介于0.9 R_Jup和1.4 R_Jup之间,质量介于0.1 M_Jup和1.5 M_Jup之间,轨道周期介于1.3天和6.6天之间。
英文摘要:
The Wide Angle Search for Planets (WASP) survey provided some of the first transiting hot Jupiter candidates. With the addition of the Transiting Exoplanet Survey Satellite (TESS), many WASP planet candidates have now been revisited and given updated transit parameters. Here we present 9 transiting planets orbiting FGK stars that were identified as candidates by the WASP survey and measured to have planetary masses by radial velocity measurements. Subsequent space-based photometry taken by TESS as well as ground-based photometric and spectroscopic measurements have been used to jointly analyze the planetary properties of WASP-102 b, WASP-116 b, WASP-149 b WASP-154 b, WASP-155 b, WASP-188 b, WASP-194 b/HAT-P-71 b, WASP-195 b, and WASP-197 b. These planets have radii between 0.9 R_Jup and 1.4 R_Jup, masses between 0.1 M_Jup and 1.5 M_Jup, and periods between 1.3 and 6.6 days.
