Revisiting wormholes supported by two non-interacting fluids

Abstract

This paper extends several previous studies of wormholes supported by two non-interacting fluids beginning with a combined model of ordinary matter and phantom dark energy with an anisotropic matter distribution. After noting that such wormholes could only exist on very large scales, the two-fluid model is extended to neutron stars, previously treated only for the isotropic case. The model is completed by incorporating certain generic features proposed by the author in an earlier study.
