Existence of traversable wormholes in the spherical stellar systems

TL;DR

This paper investigates the potential existence of traversable wormholes in galaxy halos using the Einasto density profile, showing they are possible in outer regions but not in inner regions of spiral galaxies.

Contribution

It introduces the use of the Einasto profile to analyze wormhole existence in galaxy halos, expanding beyond previous models like NFW and URC.

Findings

Traversable wormholes are possible in the outer regions of spiral galaxies.

Inner regions of galaxies do not support traversable wormholes.

The Einasto profile effectively models dark matter halos for this analysis.

Abstract

Potentiality of the presence of traversable wormholes in the outer/inner regions of the halos of galaxies, situated on the Navarro-Frenk-White (NFW) density profile and Universal Rotation Curve (URC) dark matter models have been investigated recently. Since this covers our own galaxy also as a possible home for traversable wormholes it prompts us to further the subject by considering alternative density distributions. From this token herein we make use of the Einasto model to describe the density profiles for the same purpose. Our choice for the latter is based on the fact that theoretical dark matter halos produced in computer simulations are best described by such a profile. For technical reasons we trim the number of parameters in the Einasto profile to a possible minimum. Based on such a model it is shown that traversable wormholes in the outer regions of spiral galaxies are possible while the inner part regions prohibit such formations.
