LOW STELLAR OBLIQUITIES IN COMPACT MULTIPLANET SYSTEMS

LOW STELLAR OBLIQUITIES IN COMPACT MULTIPLANET SYSTEMS

We measure the sky-projected stellar obliquities (λ) in the multiple-transiting planetary systems KOI-94 and Kepler-25, using the Rossiter-McLaughlin effect. In both cases, the host stars are well aligned with the orbital planes of the planets. For KOI-94 we find λ = -11° ± 11°, confirming a recent...
