摘要
我们报告由 WASP 巡天发现的两颗凌星系外行星：WASP-150b 和 WASP-176b。WASP-150b 是一颗偏心（e = 0.38）热木星，以 5.6 天周期环绕一颗 V = 12.03 的 F8 主序宿主星。该宿主星质量与半径分别为 1.4 M_{\odot} 和 1.7 R_{\odot}。WASP-150b 的质量与半径分别为 8.5 M_J 和 1.1 R_J，导致其较大的行星体密度为 6.4 \rho_J。WASP-150b 年龄约 3 Gyr，远低于其圆化时标，支持该行星的偏心性质。WASP-176b 是一颗热木星行星，以 3.9 天周期环绕一颗 V = 12.01 的 F9 次巨星宿主星。该宿主星质量与半径分别为 1.3 M_{\odot} 和 1.9 R_{\odot}。WASP-176b 的质量与半径分别为 0.86 M_J 和 1.5 R_J，导致其行星体密度为 0.23 \rho_J。
