Shadow of a Noncommutative Thin-Shell Gravastar
M. A. Anacleto, A. T. N. Silva, L. Casarini
One of the main challenges in astronomy is the direct observation of black holes. However, distinguishing black holes from ultra-compact horizonless objects through photon observat…

Thin-shell gravastar model in a BTZ geometry with minimum length
M. A. Anacleto, A. T. N. Silva, L. Casarini
In this paper, we construct two spherically symmetric thin-shell gravastar models within a BTZ geometry with minimum length. Therefore, in the inner region of the gravastar, we con…

Thin-shell gravastar in a noncommutative BTZ geometry
A. T. N. Silva, M. A. Anacleto, L. Casarini
In this paper, we build a thin-shell gravastar model within a noncommutative BTZ geometry. For this, we consider a noncommutative BTZ metric in the inner region and a geometry asso…
