Contribution

It introduces the concept of pure quantum gravastars and derives their metric, exploring their stability in the context of quantum gravity.

Findings

Pure quantum gravastar solutions exist within quantum-improved Einstein equations.

The metric for a quantum gravastar is explicitly derived.

Stability analysis indicates conditions under which these objects are stable.

Abstract

In this paper, we show that it is possible to have pure quantum gravastar solution to the quantum improved Einstein equations. Such an object is essentially a gravastar in which the thin layer of matter is replaced by quantum effects. The metric of a pure quantum gravastar is obtained and its stability is discussed.
