The TESS-Keck survey. IV. Rvel for WASP-107

We measured the Rossiter-McLaughlin effect of WASP-107b during a single transit with Keck/HIRES. We found the sky-projected inclination of WASP-107b's orbit, relative to its...我们借助凯克/高分辨率摄谱仪（Keck/HIRES）在单次凌星事件中，对WASP-107b的罗西特-麦克劳林效应（Rossiter-McLaughlin effect）开展了观测测量，并得到了WASP-107b轨道相对于其的天球投影倾角。
