Thin-shell wormholes with a generalized Chaplygin gas

TL;DR

This paper constructs and analyzes the stability of spherically symmetric thin-shell wormholes supported by a generalized Chaplygin gas, considering charge and cosmological constant effects, revealing both stable and unstable configurations.

Contribution

It introduces a generalized Chaplygin gas model for thin-shell wormholes and studies their stability, extending previous work on the original Chaplygin gas.

Findings

Identification of stable wormhole configurations for certain parameters

Discovery of an additional unstable solution

Comparison with previous models using original Chaplygin gas

Abstract

In this article, spherically symmetric thin-shell wormholes supported by a generalized Chaplygin gas are constructed and their stability under perturbations preserving the symmetry is studied. Wormholes with charge and with a cosmological constant are analyzed and the results are compared with those obtained for the original Chaplygin gas, which was considered in a previous work. For some values of the parameters, one stable configuration is also present and a new extra unstable solution is found.
