A window on exoplanet dynamical histories: Rossiter–McLaughlin observations of WASP-13b and WASP-32b
We present Rossiter–McLaughlin observations of WASP-13b and WASP-32b and determine the sky-projected angle between the normal of the planetary orbit and the stellar rotation axis (λ). WASP-13b and WASP-32b both have prograde orbits and are consistent with alignment with measured sky-projected angles of |$\lambda =8{^{\circ }}^{+13}_{-12}$| and |$\lambda =-2{^{\circ }}^{+17}_{-19}$|, …
