Single-charge rotating black holes in four-dimensional gauged supergravity
Single-charge rotating black holes four-dimensional gauged supergravity
2010/12/23
We consider four-dimensional U(1)^4 gauged supergravity, and obtain asymptotically AdS_4, non-extremal, charged, rotating black holes with one non-zero U(1) charge. The thermodynamic quantities are co...
Charged fermions tunneling from accelerating and rotating black holes
Charged fermions tunneling accelerating rotating black holes
2010/12/24
We study Hawking radiation of charged fermions from accelerating and rotation black holes with electric and magnetic charges. We calculate the tunneling probabilities of incoming and outgoing fermioni...

Black Holes anti-de Sitter Einstein-Gauss-Bonnet Gravity
2010/12/20
By using a new approach, we demonstrate analytic expressions for slowly rotating Gauss-Bonnet charged black holes with negative cosmological constant. Up to the linear order of the rotating parameter ...

spin parameter of uniformly compact stars
2010/12/21
We study the dimensionless spin parameter j (= cJ/(GM2)) of uniformly rotating neutron stars
and quark stars in general relativity. We show numerically that the maximum value of the spin
parameter o...
Tkachenko modes in rotating neutron stars: the effect of compressibility and implications for pulsar timing noise
Tkachenko modes rotating neutron stars effect of compressibility implications pulsar timing noise
2010/12/21
Long wavelength oscillations (Tkachenko waves) of the triangular lattice of quantized vortices in super uid neutron stars have been suggested as one of the possible explanations for the timing noise o...

Slowly rotating charged black holes in anti-de Sitter third order Lovelock gravity
charged black holes anti-de Sitter third order Lovelock gravity
2010/12/20
In this paper, we study slowly rotating black hole solutions in Lovelock gravity (n = 3). These exact slowly rotating black hole solutions are obtained in uncharged and charged cases, respectively.

Boundary value problems for the stationary axisymmetric Einstein equations: a disk rotating around a black hole
Boundary value problems black hole axisymmetric Einstein equations
2010/4/2
We solve a class of boundary value problems for the stationary axisymmetric Einstein equations corresponding to a disk of dust rotating uniformly around a central black hole. The solutions are given e...

2010/3/17
We study the evolution of magnetized and rigidly rotating neutron stars within a fully general relativistic implementation of ideal magnetohydrodynamics with no assumed symmetries in three spatial dim...
