These calculations show that gravity waves may play an important role in the dynamics of radiative zones. They can clearly explain the flat solar rotation profile without invoking the action of a magnetic field.
Work is in progress in order to compare the predictions of our model with the rotation periods of solar-type stars and their lithium abundance. The results will be used to calibrate our prescription for the wave transport, and to suggest how the present, admittedly crude treatment should be improved.
