The Zagreb indices have been introduced by Gutman and Trinajstic as M1(G) = V(G)(dG)())2 and M2(G) = vE(G) dG(u)dG(), where dG(u) denotes the degree of vertex u. We now define a new version of Zagreb indices as M*1 (G) = vE(G) [G(u)+ G()] and M*2(G)= vE(G) G(u)G(), where G(u) is the largest distance between u and any other vertex  of G. The goal of this paper is to further the study of these new topological index.
