【Abstract】 Based on plasma turbulent wave dynamo equation (p - ω dynamo equation) and using spherical polar coordinates, a set of scalar dynamo equation is obtained. Considered various rotational situations, different analytical solutions are derived. No matter the rotation angular velocity is uniform or not, the convection is absence or presence, the p -ω dynamo is operativ e. The existence of differential rotation will enhance the action of p -ω dynamo. This dynamo may explain the observed magnetic field of CP stars.更多还原
