Black Holes LIGO/Virgo Domination and Single-lined Binaries with a Black Hole Candidate Component

TL;DR

This paper discusses how LIGO/Virgo black hole detections and single-lined binaries support a scenario of conservative stellar collapse, explaining observed black hole masses, binary eccentricities, and lack of X-ray emissions.

Contribution

It links gravitational wave observations with binary star data to support a specific black hole formation scenario involving minimal mass loss during collapse.

Findings

LIGO/Virgo detection rates imply conservative stellar collapse.

Small eccentricities in binaries support minimal mass loss.

Absence of X-ray emissions aligns with the proposed collapse model.

Abstract

In this letter, we note that the observed in the LIGO / Virgo experiment ratio of the detection rate of black holes to the rate of detection of binary neutron stars requires the assumption of a "conservative" collapse of massive stars into a black hole: almost all the mass of the collapsing star goes under the horizon. This is consistent with the large masses of black holes detected by LIGO/Virgo. On the other hand, the assumption of a small loss of matter during the collapse into a black hole is in good agreement with the small eccentricity of Single-lined Binaries. At the same time, the absence of X-rays from most black holes in binary systems with blue stars is explained. We argue that three sets of LIGO / Virgo observations and data on the Single-lined Binary with a Candidate Black Hole Component confirm the scenario of the evolution of massive field binaries.
