Charged black objects in Kaluza-Klein theory — •Eugen Radu, Burkhard Kleihaus, and Jutta Kunz — Universität Oldenburg

We construct charged static black strings and p−brane solutions in a theory of gravity in D−dimensions coupled with a dilaton and an antisymmetric form by using a Harrison-type transformation. The seed vacuum solutions we use correspond to uplifted Kaluza-Klein black strings and black holes in D−p dimensions. We argue that the thermodynamics of these solutions can be derived from those of the vacuum configurations. New charged nonuniform black strings rotating in a single plane are studied in a perturbative approach for D=5,6 dimensions.
