Probing Strange Stars with Advanced Gravitational Wave Detectors

TL;DR

This paper explores the potential of advanced gravitational wave detectors to identify strange stars, which form from neutron stars at high densities, and discusses their possible link to specific gamma-ray bursts.

Contribution

It proposes that gravitational wave observations could provide evidence for strange stars and suggests their connection to certain gamma-ray bursts.

Findings

Advanced detectors may detect signals from strange star binaries.

Strange stars could be progenitors of specific gamma-ray bursts.

Non-detection of expected signals raises questions about these events.

Abstract

When a neutron star is compressed to huge densities, it may be converted to a strange star. In property of the event/year rate of a neutron star - strange star binary system, we show that the operational phase of advanced gravitational wave detectors may bring up some evidences that such strange stars do exist. Moreover we argue that such a system could be a plausible progenitor to GRB 051103 and GRB 070201, whose non-detection by LIGO last run awaits convincing explanation.
