论文摘要
我们报告了WASP-150b和WASP-176B的两种过渡性系外行星的发现。 WASP-150b是一个偏心（$ e $ = 0.38）的热木星，在5.6天的轨道上，左右$ v $ = 12.03，F8主序列主机。主机星的质量和半径为1.4 $ \ rm m _ {\ odot} $和1.7 $ \ rm r _ {\ odot} $。 WASP-150b的质量和半径为8.5 $ \ rm m_j $，1.1 $ \ rm r_j $，导致较大的行星散装密度为6.4 $ \ rmρ_j$。 WASP-150b被发现为$ \ sim3 $ gyr old，远低于其圆形时间尺度，支持地球的怪异性质。 WASP-176B是一个热门木星星球，在3.9天的轨道上，$ V $ = 12.01，F9次巨头主机。主机星的质量和半径为1.3 $ \ rm m _ {\ odot} $和1.9 $ \ rm r _ {\ odot} $。 WASP-176B的质量和半径为0.86 $ \ rm m_j $和1.5 $ \ rm r_j $，导致行星散装密度为0.23 $ \ rmρ_j$。
We report the discovery of two transiting exoplanets from the WASP survey, WASP-150b and WASP-176b. WASP-150b is an eccentric ($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 $\rm M_{\odot}$ and 1.7 $\rm R_{\odot}$ respectively. WASP-150b has a mass and radius of 8.5 $\rm M_J$ and 1.1 $\rm R_J$, leading to a large planetary bulk density of 6.4 $\rm ρ_J$. WASP-150b is found to be $\sim3$ Gyr old, well below its circularisation 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 $\rm M_{\odot}$ and 1.9 $\rm R_{\odot}$. WASP-176b has a mass and radius of 0.86 $\rm M_J$ and 1.5 $\rm R_J$ respectively, leading to a planetary bulk density of 0.23 $\rm ρ_J$.
