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.

Anisotropic gravastar as horizonless regular black hole spacetime and its images illuminated by thin accretion disk
The authors build an anisotropic gravastar model whose pressure profile and cut-off make it interpolate between a Hayward regular black hole and a horizonless ultracompact star, then compute shadow images for two accretion disk models.
