Formation and coalescence of relativistic binary stars: effect of kick velocity

For the first time, using Monte-Carlo calculations of the modern scenario for binary stellar evolution with account for spin evolution of magnetized compact stars (the “Scenario Machine”), we compute the amount of galactic binary pulsars with different companion types (OB-star, white dwarf (WD), neutron star (NS), black hole (BH), or planet) assuming various phenomenological distributions for k...

v 1 2 O ct 1 99 6 First LIGO events : binary black holes mergings

Based on evolutionary scenarios for binary stellar evolution we study the merging rates of relativistic binary stars (NS+NS, NS+BH, BH+BH) under different assumptions of BH formation. We find the BH+BH merging rate in the range one per 200,000 – 500,000 year in a Milky-Way type galaxy, while the NS+NS merging rate Rns is approximately 10 times as high, which means that the expected event rate e...

First LIGO events: binary black holes mergings

Based on evolutionary scenarios for binary stellar evolution we study the merging rates of relativistic binary stars (NS+NS, NS+BH, BH+BH) under di erent assumptions of BH formation. We nd the BH+BH merging rate in the range one per 200,000 { 500,000 year in a Milky-Way type galaxy, while the NS+NS merging rate Rns is approximately 10 times as high, which means that the expected event rate even...

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...
