A new mechanism is proposed to explain an asymmetric mass loss of carbon-rich AGB stars where slow stellar rotation modifies a wind due to the non-linear behavior of the dust formation process. This effect leads to a preferential mass loss with higher velocities in the equatorial plane and also provides a simple explanation for the widely-observed asymmetries in the shapes of planetary nebulae.
