Exact excerpt

Through the RM revolutions technique, we find that the planet is on a retrograde orbit with a derived 3D obliquity of ψ=136+24−18 deg. We find no evidence of massive outer planetary or wide stellar binary companions, which disfavors scenarios involving gravitational perturbations from a massive body and instead points toward a primordial misalignment of the protoplanetary disk.
