convective overshootThe penetration into an otherwise non-convective zone of a star of convection currents from an underlying or overlying adjacent region. In evolved stars, it may be significant in moving heavy elements from the stellar interior to outer regions that they might not otherwise reach. Evidence of convective overshoot in the Sun appears in the form of granulation at the surface.
