Global monopole solutions in Horava gravity

Abstract

In Horava's theory of gravity coupled to a global monopole source, we seek for static, spherically symmetric spacetime solutions for general values of $\lambda$. We obtain the explicit solutions with deficit solid angles, in the IR modified Horava gravity model, at the IR fixed point $\lambda =1$ and at the conformal point $\lambda =1/3$. For the other values of $1>\lambda >0$ we also find special solutions to the inhomogenous equation of the gravity model with detailed balance, and we discuss an possibility of astrophysical applications of the $\lambda =1/2$ solution that has a deficit angle for a finite range.
