Circular motion in NUT space-time — •Pavel Jefremov and Volker Perlick — ZARM, Universität Bremen

We investigate characteristic imprints of the gravitomagnetic charge and the Manko-Ruiz constant on circular geodesics and perfect fluid tori motion in NUT (Newman-Unti-Tamburino) metric. For the perfect fluid case we consider the Polish Doughnuts model which is widely used in modelling of accretion flows. We find that the shape of the rotational configurations is qualitatively changed due to the presence of the gravitomagnetic charge and compare thermodynamical parameters of the tori for different values of the parameters of the metric.
