Metric for two unequal extreme Kerr-Newman black holes

I. Cabrera-Munguia (Departamento de Física y Matemáticas, Universidad Autónoma de Ciudad Juárez, 32310 Ciudad Juárez, Chihuahua, Mexico)

In the present paper, within the framework of stationary axisymmetric spacetimes, binary systems composed of two unequal co- and counter-rotating extreme Kerr-Newman black holes separated by a massless strut are reported. The metric describing both configurations is introduced in a closed analytical form in terms of five arbitrary parameters: the masses Mi, electric charges Qi, and a coordinate distance R. We obtain novel results from these configurations; in particular, those related to the merging process.
