When the mesh is refined a new partitioning between processors is used. Therefore, ghost cells and artificial are not really refined but set accordingly after the mesh is refined.

If you are using a parallel::distributed Triangulation and move vertices that are in someone's ghost layer, you should call Triangulation::communicate_locally_moved_vertices [1] to have a consistent mesh. You need to be careful if you want to refine the mesh after you have moved vertices as noted in the documentary of that function.
