The observation of certain longitudes on stars which show persistent activity requires non‐axisymmetric dynamo solutions which coexist with the typical axisymmetric, oscillatory dynamo solutions known from mean‐field α ‐dynamos. This study is an attempt of finding non‐axisymmetric solutions arising from large‐scale flows with meridional circulation and a differential rotation imitating the ones in stars.
