摘要：
Abundances anomalies and helioseismology provide constraints on the turbulent transport of chemical species in stellar radiative zone. We use these constraints to derive upper bounds oil the velocity and lengthscale of the vertical turbulent motions. We also present numerical simulations showing that a strong anisotropy between horizontal and vertical motions could help understand the observed transport.
