A theory of thin shells with orbiting constituents

TL;DR

This paper develops a theoretical model of self-gravitating thin shells composed of orbiting particles, revealing new features like a minimal angular momentum and the coexistence of wormhole and orbit solutions, with potential astrophysical and quantum black hole applications.

Contribution

It introduces a novel theoretical framework for thin shells with orbiting constituents, uncovering minimal angular momentum and coexistence of different orbit types.

Findings

Existence of a minimal angular momentum for orbiting particles.

Coexistence of wormhole solutions and elliptical or hyperbolic orbits.

Potential implications for astrophysics and quantum black holes.

Abstract

The self-gravitating, spherically symmetric thin shells built of orbiting particles are sstudied. Two new features are found. One is the minimal possible value for an angular momentum of particles, above which elleptic orbits become possible. The second is the coexistence of both the wormhole solutions and the elleptic or hyperbolic orbits for the same values of the parameters (but different initial conditions). Possible applications of these results to astrophysics and quantum black holes are briefly discussed.
