Beyond the Bowen-York extrinsic curvature for spinning black holes
نویسندگان
چکیده
It is well-known that Bowen-York initial data contain spurious radiation. Although this “junk” radiation has been seen to be small for non-spinning black-hole binaries in circular orbit, its magnitude increases when the black holes are given spin. It is possible to reduce the spurious radiation by applying the puncture approach to multiple Kerr black holes, as we demonstrate for examples of head-on collisions of equal-mass black-hole binaries.

Binary-black-hole initial data with nearly extremal spins
There is a significant possibility that astrophysical black holes with nearly extremal spins exist. Numerical simulations of such systems require suitable initial data. In this paper, we examine three methods of constructing binary-black-hole initial data, focusing on their ability to generate black holes with nearly extremal spins: (i) Bowen-York initial data, including standard puncture data ...
متن کاملTidal deformations of spinning black holes in Bowen-York initial data
We study the tidal deformations of the shape of a spinning black hole horizon due to a binary companion in the Bowen-York initial data set. We use the framework of quasi-local horizons and identify a black hole by marginally outer trapped surfaces. The intrinsic horizon geometry is specified by a set of mass and angularmomentum multipole moments Mn and Jn respectively. The tidal deformations ar...
متن کاملGeneralized Bowen–York Initial Data
A class of vacuum initial-data sets is described which are based on certain expressions for the extrinsic curvature first studied and employed by Bowen and York. These expressions play a role for the momentum constraint of General Relativity which is analogous to the role played by the Coulomb solution for the Gauss-law constraint of electromagnetism.
متن کاملExtreme Bowen-York initial data
The Bowen-York family of spinning black hole initial data depends essentially on one, positive, free parameter. The extreme limit corresponds to making this parameter equal to zero. This choice represents a singular limit for the constraint equations. We prove that in this limit a new solution of the constraint equations is obtained. These initial data have similar properties to the extreme Ker...
متن کاملSpinning Black Holes in (2 + 1)-dimensional String and Dilaton Gravity
We present a new class of spinning black hole solutions in (2+1)-dimensional general relativity minimally coupled to a dilaton with potential ebφΛ. When b = 4, the corresponding spinning black hole is a solution of low energy (2 + 1)-dimensional string gravity. Apart from the limiting case of the BTZ black hole, these spinning black holes have no inner horizon and a curvature singularity only a...
