Secular Evolution of Hierarchical Triple Star Systems

We derive octupole-level secular perturbation equations for hierarchical triple systems, using classical Hamiltonian perturbation techniques. Our equations describe the secular evolution of the orbital eccentricities and inclinations over timescales long compared to the orbital periods. By extending previous work done to leading (quadrupole) order to octupole level (i.e., including terms of ord...

Binary systems and stellar mergers in massive star formation

We present a model for the formation of high-mass close binary systems in the context of forming massive stars through gas accretion in the centres of stellar clusters. A low-mass wide binary evolves under mass accretion towards a high-mass close binary, attaining system masses of order 30-50 M⊙at separations of order 1 AU. The resulting high frequency of binary systems with two massive compone...

Black hole binary mergers

I overview the current understanding of the evolution of massive black hole (MBH) binaries in the center of the host stellar system. One of the main questions is whether the stellar dynamical effect can make the MBH binary hard enough that they can merge through gravitational wave radiation. So far, theories and numerical simulations suggested otherwize, since the hardening timescale becomes ve...

Binary Neutron Star Mergers

We review the current status of studies of the coalescence of binary neutron star systems. We begin with a discussion of the formation channels of merging binaries and we discuss the most recent theoretical predictions for merger rates. Next, we turn to the quasi-equilibrium formalisms that are used to study binaries prior to the merger phase and to generate initial data for fully dynamical sim...

Binary black hole mergers

www.physicstoday.org After decades of effort, numerical relativists can now simulate the inspiral and merger of two black holes orbiting each other. That computational triumph has come none too soon—physicists are on the verge of detecting gravitational waves for the first time, and at long last they know what to look for. Black holes are strong-field objects whose properties are governed by Ei...
