We investigate the influence of noninertial effects on the ground stateenergy of a massive scalar field in the cosmic string spacetime. We generalizethe results obtained by Khusnutdinov and Bordag [N. R. Khusnutdinov and M.Bordag, Phys. Rev. D 59, 064017 (1999)] to a noninertial reference frame andshow, by contrast, that a non-vanishing contribution to the ground state energystems from the noninertial effects. Moreover, we show that there is noinfluence of the curvature of the spacetime on this non-vanishing contributionto the ground state energy of a massive scalar field.
