Prospects for gravitational-wave observations of neutron-star tidal disruption in neutron-star-black-hole binaries.
For an inspiraling neutron-star-black-hole (NS-BH) binary, we estimate the gravity-wave frequency f(td) at the onset of NS tidal disruption. We model the NS as a tidally distorted, homogeneous, Newtonian ellipsoid on a circular, equatorial geodesic around a Kerr BH. We find that f(td) depends strongly on the NS radius R, and estimate that LIGO-II (ca. 2006-2008) might measure R to 15% precision...
متن کاملPrimordial black hole constraints in cosmologies with early matter domination
Moduli fields, a natural prediction of any supergravity and superstring-inspired supersymmetry theory, may lead to a prolonged period of matter domination in the early Universe. This can be observationally viable provided the moduli decay early enough to avoid harming nucleosynthesis. If primordial black holes form, they would be expected to do so before or during this matter dominated era. We ...
متن کاملCoalescence of Black Hole-Neutron Star Binaries
We review the current status of general relativistic studies for the coalescence of black hole-neutron star (BH-NS) binaries. First, procedures for a solution of BH-NS binaries in quasi-equilibrium circular orbits and the numerical results, such as quasi-equilibrium sequence and mass-shedding limit, of the high-precision computation, are summarized. Then, the current status of numerical-relativ...
متن کاملMassive disk formation in the tidal disruption of a neutron star by a nearly extremal black hole
Black hole–neutron star (BHNS) binaries are important sources of gravitational waves for second-generation interferometers, and BHNS mergers are also a proposed engine for short, hard gamma-ray bursts. The behavior of both the spacetime (and thus the emitted gravitational waves) and the neutron star matter in a BHNS merger depend strongly and nonlinearly on the black hole’s spin. While there is...
متن کاملSupersymmetry and primordial black hole abundance constraints
and MBH is the PBH mass in grams. The standard picture of PBH evaporation is that all particles which appear elementary at the energy scale of the PBH and have rest mass less than TBH are emitted directly [3]. For instance PBHs with TBH above the QCD quark-hadron transition scale ΛQH ≈ 250− 300 MeV, emit relativistic quark and gluon jets which then fragment into photons, leptons and hadrons as ...
