Slices of the Kerr ergosurface
نویسنده
چکیده
The intrinsic geometry of the Kerr ergosurface on constant BoyerLindquist (BL), Kerr, and Doran time slices is characterized. Unlike the BL slice, which had been previously studied, the other slices (i) do not have conical singularities at the poles (except the Doran slice in the extremal limit), (ii) have finite polar circumference in the extremal limit, and (iii) for sufficiently large spin parameter fail to be isometrically embeddable as a surface of revolution above some latitude. The Doran slice develops an embeddable polar cap for spin parameters greater than about 0.96. E-mail: [email protected] E-mail: [email protected] 1 ar X iv :0 80 9. 23 69 v2 [ gr -q c] 1 9 Fe b 20 09

متن کاملQuasilocal energy for a Kerr black hole.
The quasilocal energy associated with a constant stationary time slice of the Kerr spacetime is presented. The calculations are based on a recent proposal [1] in which quasilocal energy is derived from the Hamiltonian of spatially bounded gravitational systems. Three different classes of boundary surfaces for the Kerr slice are considered (constant radius surfaces, round spheres, and the ergosu...
متن کاملZel’dovich-Starobinsky Effect in Atomic Bose-Einstein Condensates: Analogy to Kerr Black Hole
We consider circular motion of a heavy object in an atomic Bose-Einstein condensate (BEC) at T = 0K. Even if the linear velocity of the object is smaller than the Landau critical velocity, the object may radiate quasiparticles and thus experience the quantum friction. The radiation process is similar to Zel'dovich-Starobinskii (ZS) effect – the radiation by a rotating black hole. This analogy e...
متن کاملAsymptotic expansions of the Cotton-York tensor on slices of stationary spacetimes
We discuss expansions for the Cotton-York tensor near infinity for arbitrary slices of stationary spacetimes. From these expansions it follows directly that a necessary condition for the existence of conformally flat slices in stationary solutions is the vanishing of a certain quantity of quadrupolar nature (obstruction). The obstruction is nonzero for the Kerr solution. Thus, the Kerr metric a...
متن کاملInfluence of optical Kerr coefficient on photonic band structures of hexagonal-lattice function photonic crystals
In this paper, we have studied the photonic band structure of function photonic crystals in which the dielectric constant of the scattering centers (rods) is a function of space coordinates. The under-studied lattice is hexagonal and cross section of rods has a circular symmetry embedded in the air background. Photonic band structures for both electric and magnetic polarizations of the electrom...
