All static spherically symmetric anisotropic solutions of Einstein's equations
L. Herrera, J. Ospino, A. Di Prisco
An algorithm recently presented by Lake to obtain all static spherically symmetric perfect fluid solutions, is extended to the case of locally anisotropic fluids (principal stresse…
Frame dragging and super-energy
L. Herrera, J. Carot, A. Di Prisco
We show that the vorticity appearing in stationary vacuum spacetimes is always related to the existence of a flow of super-energy on the plane orthogonal to the vorticity vector. T…
Why does gravitational radiation produce vorticity?
L. Herrera, W. Barreto, J. Carot +1
We calculate the vorticity of world--lines of observers at rest in a Bondi--Sachs frame, produced by gravitational radiation, in a general Sachs metric. We claim that such an effec…
The Thomas precession and the transformation to rotating frames
L. Herrera, A. Di Prisco
The Thomas precession is calculated using three different transformations to the rotating frame. It is shown that for sufficiently large values of , important differences in t…
