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 (\(\lambda\)). 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 \(\lambda={-2^{\circ}}^{+17}_{-19}\), respectively. Both WASP-13 and WASP-32 have \(T_{\mathrm{eff}}
