Reliability analysis is important to the design of large multiprocessor systems. Connectivity, super connectivity and extra connectivity are important parameters to evaluate the reliability of multiprocessor systems. As a generalization of connectivity and super connectivity, extra connectivity has received much research attentions. The h-extra connectivity of the star graph (kappa(h)(S-n)) for h = 1, 2 have been obtained by Cheng et al. for n >= 3, n >= 4, respectively. In this paper, we extend their results. The h-extra connectivity of the star graph for h = 3,4 is determined as follows: kappa(h)(S-n) = (h + 1)n - 4h + 2 for h = 3,4 and n >= 7.
