In a globular cluster, hierarchical triple black hole systems can be produced through binary-binary interaction. It has been proposed recently that the Kozai mechanism could drive the inner binary of the triple system to merge before it is interrupted by interactions with other field stars. We investigate qualitatively and numerically the evolution of the eccentricities in these binaries under gravitational radiation (GR) reaction. We predict that ~30% of the systems will possess eccentricities… 


Coalescing black hole (BH) binaries forming in the dense core of globular clusters (GCs) are expected to be one of the brightest sources of gravitational wave (GW) radiation for the next generation

Tidal effects in eccentric coalescing neutron star binaries

Dynamically formed compact object binaries may still be eccentric while in the LIGO/Virgo band. For a neutron star (NS) in an eccentric binary, the fundamental modes (f-modes) are excited at

Probabilistic eccentricity bifurcation for stars around shrinking massive black hole binaries

Based on the secular theory, we discuss the orbital evolution of stars in a nuclear star cluster to which a secondary massive black hole is infalling with vanishing eccentricity. We find that the

Eccentric compact binaries: modeling the inspiral and gravitational wave emission

The modeling of the inpsiral and subsequent gravitational wave emission from black hole binary systems has been a long outstanding problem in astrophysics and relativity. Astrophysical models predict

Detecting Supermassive Black Hole–induced Binary Eccentricity Oscillations with LISA

Stellar-mass black hole binaries (BHBs) near supermassive black holes (SMBH) in galactic nuclei undergo eccentricity oscillations due to gravitational perturbations from the SMBH. Previous works have

Post-Newtonian Dynamics in Dense Star Clusters: Highly Eccentric, Highly Spinning, and Repeated Binary Black Hole Mergers.

Modelling the relativistic accelerations and gravitational-wave emission in isolated binaries and during three- and four-body encounters finds that nearly half of all binary black hole mergers occur inside the cluster, with about 10% of those mergers entering the LIGO/Virgo band with eccentricities greater than 0.1.

Black Hole Mergers in Galactic Nuclei Induced by the Eccentric Kozai–Lidov Effect

Nuclear star clusters around a central massive black hole (MBH) are expected to be abundant in stellar black hole (BH) remnants and BH–BH binaries. These binaries form a hierarchical triple system

Black hole mergers and blue stragglers from hierarchical triples formed in globular clusters

Hierarchical triple-star systems are expected to form frequently via close binary–binary encounters in the dense cores of globular clusters (GCs). In a sufficiently inclined triple, gravitational

Black Hole Mergers from Hierarchical Triples in Dense Star Clusters

Hierarchical triples are expected to be produced by the frequent binary-mediated interactions in the cores of globular clusters. In some of these triples, the tertiary companion can drive the inner

The Impact of Vector Resonant Relaxation on the Evolution of Binaries near a Massive Black Hole: Implications for Gravitational-wave Sources

Binaries within the sphere of influence of a massive black hole (MBH) in galactic nuclei are susceptible to the Lidov–Kozai (LK) mechanism, which can drive orbits to high eccentricities and trigger



The Kozai Mechanism and the Evolution of Binary Supermassive Black Holes

We consider the dynamical evolution of bound, hierarchical triples of supermassive black holes that might be formed in the nuclei of galaxies undergoing sequential mergers. The tidal force of the

Four-Body Effects in Globular Cluster Black Hole Coalescence

In the high-density cores of globular clusters, multibody interactions are expected to be common, with the result that black holes in binaries are hardened by interactions. It was shown by Sigurdsson

Black Hole Mergers in the Universe

This Letter explores the possibility that black holes become members of close binaries via dynamical interactions with other stars in dense stellar systems, implying gravity-wave detection rates substantially greater than the corresponding rates from neutron star mergers.

Spectral Analysis of the Gravitational Radiation Emitted by Binary Systems in Moderately Eccentric Orbits - Application to Coalescing Binaries

We obtain the form of the gravitational waves emitted by eccentric binary systems, including general relativistic periastron advance effects. Using the method of stationary phase, we find the Fourier

The Mass Distribution of Stellar Black Holes

We examine the distribution of masses of black holes in transient low-mass X-ray binary systems. A Bayesian analysis suggests that it is probable that six of the seven systems with measured mass

Gravitational Radiation from Intermediate-Mass Black Holes

Recent X-ray observations of galaxies with ROSAT, ASCA, and Chandra have revealed numerous bright off-center point sources that, if isotropic emitters, are likely to be intermediate-mass black holes,

Tidal interactions in star cluster simulations

ABSTRA C T We describe the implementation of tidal circularization of binaries in an N-body code for star cluster simulations. The first part contains the theoretical framework for normal and chaotic

We investigate the problem of detecting gravitational waves from binaries of nonspinning black holes with masses m=5-20M., moving on quasicircular orbits, which are arguably the most promising

The late-time evolution of binary systems of compact objects (neutron stars or black holes) is studied using the Damour-Deruelle (post){sup 5/2}-Newtonian equations of motion with relativistic
