Evolution of Binary Compact Objects Which Merge
Beginning from massive binaries in the Galaxy we evolve black–hole, neutron–star binaries and binary neutron stars, such as the Hulse–Taylor system PSR 1913+16. The new point in our evolution is a quantitative calculation of the accretion of matter by a neutron star in common envelope evolution which sends it into a black hole. We calculate the mass of the latter to be ∼ 2.4 M⊙. The black hole ...
متن کاملMergers of Binary Compact Objects
We work out the effects of hypercritical accretion, which transfers mass from the secondary to the primary (first-born) neutron star (NS) in a binary, showing that the mass of the primary would end up ∼ > 0.6M⊙ greater than the secondary NS in contradiction with the very nearly equal masses of the two NS’s in binaries measured to date. We discuss that the primary NS evolves into a low-mass blac...
متن کاملThe Evolution of Compact Binary Star Systems
We review the formation and evolution of compact binary stars consisting of white dwarfs (WDs), neutron stars (NSs), and black holes (BHs). Binary NSs and BHs are thought to be the primary astrophysical sources of gravitational waves (GWs) within the frequency band of ground-based detectors, while compact binaries of WDs are important sources of GWs at lower frequencies to be covered by space i...
متن کاملSpin-Orbit Resonance and the Evolution of Compact Binary Systems
Starting with a post-Newtonian description of compact binary systems, we derive a set of equations that describes the evolution of the orbital angular momentum and both spin vectors during inspiral. We find regions of phase space that exhibit resonance behavior, characterized by small librations of the spin vectors around a fixed orientation. Due to the loss of energy and orbital angular moment...
متن کاملLong-term remnant evolution of compact binary mergers
We investigate the long-term evolution and observability of remnants originating from the merger of compact binary systems and discuss the differences to supernova remnants. Compact binary mergers expel much smaller amounts of mass at much higher velocities, as compared to supernovae and therefore the free expansion phase of the remnant will be short (∼ 1 10 yr). But merger events with high mas...
