 Title: Conformally flat sources for the linet-tian spacetime Author(s): Brito, IreneSilva, M. F. A. daMena, Filipe C.Santos, N. O. Keywords: Exact solutionsCylindrical symmetrySpacetime matching Issue date: Feb-2013 Publisher: Springer Journal: General Relativity and Gravitation Abstract(s): We investigate the matching, across cylindrical surfaces, of static cylindrically symmetric conformally flat spacetimes with a cosmological constant $\Lambda$, satisfying regularity conditions at the axis, to an exterior Linet-Tian spacetime. We prove that for $\Lambda\leq 0$ such matching is impossible. On the other hand, we show through simple examples that the matching is possible for $\Lambda>0$. We suggest a physical argument that might explain these results.
