Phys. Rev. D 74, 067703 (2006) [4 pages]Local cosmic strings in Brans-Dicke theory with a cosmological constantReceived 9 August 2006; published 25 September 2006 It is known that Vilenkin’s phenomenological equation of state for static straight cosmic strings is inconsistent with Brans-Dicke theory. We will prove that, in the presence of a cosmological constant, this equation of state is consistent with Brans-Dicke theory. The general solution of the full nonlinear field equations, representing the interior of a cosmic string with a cosmological constant, is also presented. © 2006 The American Physical Society URL:
