The curious case of the Buchdahl-Land-Sultana-Wyman-Ibañez-Sanz spacetime
arXiv:2110.11289 · doi:10.1103/PhysRevD.105.024030
Abstract
We revisit Wyman's "other" scalar field solution of the Einstein equations and its Sultana generalization to positive cosmological constant, which has a finite 3-space and corresponds to a special case of a stiff fluid solution proposed by Buchdahl and Land and, later, by Ibañez and Sanz to model relativistic stars. However, there is a hidden cosmological constant and the peculiar geometry prevents the use of this spacetime to model relativistic stars.
