Rotation curves, dark matter and general relativity
Abstract
We study the possibility of pure general relativistic models without exotic matter to describe the observed flattening of the rotation curves for stars moving in circular orbits in a galaxy disk. In particular we consider the dragging of inertial frames (rotation of the source) and the presence of a Taub-NUT (Newman-Unti-Tamburino) "charge", the gravitational equivalent to a magnetic monopole in electrodynamics.
