It is well known that graph spectra store a lot of structural information about a graph,and it is more difficult to compute the spectra of corona graphs.In this paper two classes of new corona graphs,the corona-vertex of the subdivision graph G1◇G2 and corona-edge of the subdivision graph G1 ☆ G2 were defined.Then,by using the coronal of a graph and some knowledge of linear algebra,the adjacency spectra and the signless Laplacian spectra of the two new graphs were explicitly computed in terms of the corresponding spectra of G1 and G2.As the application,some Aintegral graphs were constructed.
