Dilatonic Black Saturn — •Saskia Grunau and Jutta Kunz — Universität Oldenburg

We construct the charged rotating black saturn in Einstein-Maxwell-dilaton theory in five dimensions. The black saturn solution of Elvang and Figueras is embedded in six dimensions and boosted with respect to the time coordinate and the added sixth dimension. Then the charged solution is obtained by a Kaluza-Klein reduction.

If the parameters of the solution satisfy certain conditions, the dilatonic black saturn is in mechanical and thermodynamical equilibrium at the same time.

We study the influence of the dilaton on the black saturn spacetime by analysing the physical properties and the phase diagram.
