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.\n  Both WASP-13 and WASP-32 have $T_{\\mathrm{eff}}<6250$K and therefore these systems support the general trend that aligned planetary systems are preferentially found orbiting cool host stars.
