In the study by Zhou et al. (2016), there appears to be no evidence that the rotation rates of the host stars of KELT-7b and HAT-P-56b have been modified by star-planet tidal interactions. This indicates that the current spin-orbit angles of KELT-7b and HAT-P-56b most likely represent their initial configurations right after they have migrated towards their host stars via planet-gas interactions in the protoplanetary disk.
