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…
