Query: Solar-like differential rotation and equatorward migration in a
  convective dynamo with a coronal envelope   We present results of convective turbulent dynamo simulations including a
coronal layer in a spherical wedge. We find an equatorward migration of the
radial and azimuthal fields similar to the behavior of sunspots during the
solar cycle. The migration of the field coexist with a spoke-like differential
rotation and anti-solar (clockwise) meridional circulation. Even though the
migration extends over the whole convection zone, the mechanism causing this is
not yet fully understood.
