Canuto, V.M., 1999: Overshooting in massive stars: Conceptual problems and suggested solution. Astrophys. J., 518, L119-L122, doi:10.1086/312082.

Overshooting (OV) in massive stars faces a basic difficulty: what theoretical models offer is not what stellar structure studies need. The former use ∇μ and define the OV where the negative convective flux J vanishes, while the latter need to know where the concentration flux Jc vanishes. We suggest that J may be dynamically irrelevant and derive the new dynamic equations for Jc. A new feature emerges: for large concentration gradients ∇C, Jc is no longer proportional to ∇C, as always assumed.
