WASP-31b and host star radius compared with IMACS

We present a new optical (400-950nm) transmission spectrum of the hot Jupiter WASP-31b (M=0.48M_Jup_; R=1.54R_Jup_; P=3.41days), obtained by combining four transit observations....本研究报道了热木星WASP-31b的全新光学（400~950nm）透射光谱，该行星质量为0.48M_Jup、半径为1.54R_Jup、公转周期为3.41天，此光谱通过整合四次凌日观测获得。
