Gravitational-wave Emission from a Primordial Black Hole Inspiraling inside a Compact Star: A Novel Probe for Dense Matter Equation of State

چکیده
Abstract Primordial black holes of planetary masses captured by compact stars are widely studied to constrain their composition fraction dark matter. Such a capture may lead an inspiral process and be detected through gravitational-wave signals. In this Letter, we study the postcapture considering two different kinds stars, i.e., strange neutron stars. The dynamical equations numerically solved, emission is calculated. It found that Advanced LIGO can detect inspiraling 10 −5 M ⊙ primordial hole at distance kpc, while Jovian-mass case even megaparsecs. Promisingly, next generation detectors cases up ∼1Mpc several hundred Moreover, kilohertz signal shows significant differences for potentially making it novel probe dense matter equation state.

Neutron Star Matter Equation of State and Gravitational Wave Emission
The EOS of strongly interacting matter at densities ten to fifteen orders of magnitude larger than the typical density of terrestrial macroscopic objects determines a number of neutron star properties, including the pattern of gravitational waves emitted following the excitation of nonradial oscillation modes. This paper reviews some of the approaches employed to model neutron star matter, as w...
متن کاملPrimordial Black Hole Scenario for the Gravitational-Wave Event GW150914.
We point out that the gravitational-wave event GW150914 observed by the LIGO detectors can be explained by the coalescence of primordial black holes (PBHs). It is found that the expected PBH merger rate would exceed the rate estimated by the LIGO Scientific Collaboration and the Virgo Collaboration if PBHs were the dominant component of dark matter, while it can be made compatible if PBHs const...
متن کاملGravitational waves from sub-lunar-mass primordial black-hole binaries: a new probe of extradimensions.
In many brane world models, gravity is largely modified at the electroweak scale approximately 1 TeV. In such models, primordial black holes (PBHs) with a lunar mass M approximately 10(-7)M([circle dot]) might have been produced when the temperature of the Universe was at approximately 1 TeV. If a significant fraction of the dark halo of our galaxy consists of these lunar mass PBHs, a huge numb...
متن کاملShock-wave cosmology inside a black hole.
We construct a class of global exact solutions of the Einstein equations that extend the Oppeheimer-Snyder model to the case of nonzero pressure, inside the black hole, by incorporating a shock wave at the leading edge of the expansion of the galaxies, arbitrarily far beyond the Hubble length in the Friedmann-Robertson-Walker (FRW) spacetime. Here the expanding FRW universe emerges be-hind a su...
متن کاملGravitational waves from inspiraling binary black holes
Binary black holes are the most promising candidate sources for the first generation of earth-based interferometric gravitational-wave detectors. We summarize and discuss the state-of-the-art analytic techniques developed during the last years to better describe the late dynamical evolution of binary black holes of comparable masses.
