On the evolution of compact binary black holes

TL;DR

This paper investigates the potential matter transfer between black holes in a binary system, analyzing conditions for merger and gravitational wave emission based on energy considerations and system mass sensitivity.

Contribution

It introduces a novel approach considering matter transfer dynamics in binary black holes and examines how total system mass influences merger conditions.

Findings

Matter transfer between black holes is theoretically possible.

Merger conditions depend on total mass and energy transfer dynamics.

Gravitational wave emission is linked to the matter transfer process.

Abstract

Based on the consideration of potential energy of the di-black-hole as a function of mass asymmetry (transfer) collective coordinate, the possibility of matter transfer between the black holes in a binary system is investigated. The sensitivity of the calculated results is studied to the value of the total mass of binary system. The conditions for the merger of two black holes are analyzed in the context of gravitational wave emission.
