Trapping and guiding bodies by gravitational waves endowed with angular momentum

TL;DR

This paper explores how gravitational waves with angular momentum can trap cosmic debris, similar to electromagnetic waves, potentially explaining phenomena like asteroid libration and galactic jet formation.

Contribution

It extends wave trapping concepts from electromagnetism to gravity, revealing a mechanism involving the Coriolis force for trapping bodies near gravitational wave centers.

Findings

Gravitational waves with angular momentum can trap cosmic debris.

The trapping mechanism is linked to the Coriolis force from local space rotation.

Potential implications for galactic jet formation and asteroid libration.

Abstract

Trapping of bodies by waves is extended from electromagnetism to gravity. It is shown that gravitational waves endowed with angular momentum may accumulate near its axis all kinds of cosmic debris. The trapping mechanism in both cases can be traced to the Coriolis force associated with the local rotation of the space metric. The same mechanism causes the Trojan asteroids to librate around the Sun-Jupiter stable Lagrange points $L_4$ and $L_5$. Trapping of bodies in the vicinity of the wave center could also be related to the formation of galactic jets.
