The energy of a graph G is the sum of the absolute values of the eigenvalues of the adjacency matrix of G. A caterpillar is a tree in which the removal of all pendant vertices makes it a path. Let d 3 and n Let C(p) be the caterpillar obtained from the stars S p 1 +1 , S p 2 +1 , . . . , S p d-1 +1
