Wormholes supported by two non-interacting fluids

TL;DR

This paper introduces a new matter source involving anisotropic dark energy to support wormhole spacetimes, demonstrating that such exotic matter can satisfy certain energy conditions while maintaining positive effective mass.

Contribution

It presents exact wormhole solutions supported by a novel combination of real matter and anisotropic dark energy, expanding the understanding of matter sources capable of sustaining wormholes.

Findings

Exotic matter violates null and weak energy conditions but obeys strong energy condition marginally.

The effective mass of the wormhole is positive, calculated as 1.3559 solar masses.

Wormhole features are briefly discussed, supporting the feasibility of such models.

Abstract

We provide a new matter source that supplies fuel to construct wormhole spacetime. The exact wormhole solutions are found in the model having, besides real matter, an anisotropic dark energy. We have shown that the exotic matters that are the necessary ingredients for wormhole physics violate null and weak energy conditions but obey strong energy condition marginally. Though the wormhole comprises of exotic matters yet the effective mass remains positive. We have calculated the effective mass of the wormhole up to 8 km from the throat (assuming throat radius as 4 km) as $1.3559M_\odot $. Some physical features are briefly discussed.
