  • 摘要: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 ${M}_{\odot }$ and 1.7 ${R}_{\odot }$ respectively.WASP-150b has a mass and radius of 8.5 ${M}_{{\rm{J}}}$ 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.
