Weighted Vogan diagrams associated to real nilpotent orbits

We associate to each nilpotent orbit of a real semisimple Lie algebra g(o) a weighted Vogan diagram, that is a Dynkin diagram with an involution of the diagram, a subset of painted nodes and a weight for each node. Every nilpotent element of g(o) is noticed in some subalgebra of g(o). In this paper we characterize the weighted Vogan diagrams associated to orbits of noticed nilpotent elements.
