Anisotropic Stars in General Relativity

We present a class of exact solutions of Einstein’s gravitational field equations describing spherically symmetric and static anisotropic stellar type configurations. The solutions are obtained by assuming a particular form of the anisotropy factor. The energy density and both radial and tangential pressures are finite and positive inside the anisotropic star. Numerical results show that the ba...

Conformally Flat Anisotropic Spheres in General Relativity

The condition for the vanishing of the Weyl tensor is integrated in the spherically symmetric case. Then, the resulting expression is used to find new, conformally flat, interior solutions to Einstein equations for locally anisotropic fluids. The slow evolution of these models is contrasted with the evolution of models with similar energy density or radial pressure distribution but non-vanishin...

Anisotropic Geodesic Fluid Spheres in General Relativity

It is shown that unlike the perfect fluid case, anisotropic fluids (principal stresses unequal) may be geodesic, without this implying the vanishing of (spatial) pressure gradients. Then the condition of vanishing four acceleration is integrated in non-comoving coordinates. The resulting models are necessarily dynamic, and the mass function is expressed in terms of the fluid velocity as measure...

Irrotational Binary Neutron Stars in Quasiequilibrium in General Relativity

Neutron stars in binary orbit emit gravitational waves and spiral slowly together. During this inspiral, they are expected to have very little vorticity. It is in fact a good approximation to treat the system as having zero vorticity, i.e., as irrotational. Because the orbital period is much shorter than the radiation reaction time scale, it is also an excellent approximation to treat the syste...

A Numerical Study of Solitonic Boson Stars in General Relativity

In the wake of the recent detection of gravitational wave signal GW150914, we investigate whether GW150914 could have been produced by something other than a binary black hole system. Our proposed candidate is a binary system of solitonic boson stars. The choice of solitonic boson stars is due mainly to the structural properties of their ground states, as solitonic boson stars are capable of fo...
