<jats:title>Abstract</jats:title> <jats:p>A scheme of Bayesian rotation inversion, which allows us to compute the probability of a model of a stellar rotational profile, is developed. The validation of the scheme with simple rotational profiles and the corresponding sets of artificially generated rotational shifts has been successfully carried out, and we can correctly distinguish the (right) rotational model, prepared beforehand for generating the artificial rotational shifts, from the other (wrong) rotational model. The Bayesian scheme is applied to a <jats:italic>γ</jats:italic> Dor–<jats:italic>δ</jats:italic> Sct-type hybrid star, KIC 11145123, leading to a result that the convective core of the star might be rotating much faster (∼10 times faster) than the other regions of the star. The result is consistent with that previously suggested by Hatta et al. based on a three-zone modeling, further strengthening their argument from a Bayesian point of view.</jats:p>
