我们报告在 WASP 巡天中发现了两颗凌日系外行星:WASP-150b 和 WASP-176b。 WASP-150b 是一颗偏心 (e = 0.38) 的热木星,绕 V = 12.03、F8 主序宿主运行 5.6 天的轨道。主星的质量和半径分别为1.4和1.7。 WASP-150b 的质量和半径分别为 8.5 和 1.1 RJ,导致行星体积密度高达 6.4 ρJ。 WASP-150b 的年龄约为 3 吉里,远低于其圆化时间尺度,支持了该行星的偏心性质。 WASP-176b 是一颗热木星行星,围绕 V = 12.01、F9 亚巨星宿主运行 3.9 天的轨道。主星的质量和半径分别为1.3 M⊙和1.9 R⊙。 WASP-176b 的质量和半径分别为 0.86 MJ 和 1.5 RJ,导致行星体积密度为 0.23 ρJ。
We report the discovery of two transiting exoplanets from the WASP survey, WASP-150b and WASP-176b. WASP-150b is an eccentric (e = 0.38) hot Jupiter on a 5.6 day orbit around a V = 12.03, F8 main-sequence host. The host star has a mass and radius of 1.4 and 1.7 respectively. WASP-150b has a mass and radius of 8.5 and 1.1 RJ, leading to a large planetary bulk density of 6.4 ρJ. WASP-150b is found to be ∼3 Gyr old, well below its circularization timescale, supporting the eccentric nature of the planet. WASP-176b is a hot Jupiter planet on a 3.9 day orbit around a V = 12.01, F9 sub-giant host. The host star has a mass and radius of 1.3 M⊙ and 1.9 R⊙. WASP-176b has a mass and radius of 0.86 MJ and 1.5 RJ, respectively, leading to a planetary bulk density of 0.23 ρJ.
