Abstract
We have succeeded in obtaining highly relativistic structures of stationary axisymmetric configurations consisting of massive complex scalar fields, i.e., rotating boson stars. Scalar fields are assumed to have harmonic azimuthal angular dependence, i.e., , where is an integer. Equilibrium configurations are characterized by values of so that the total angular momentum of the boson star becomes discrete. We have solved sequences of equilibrium states with and by changing one parameter which characterizes the model. The maximum mass for models is , where and are the Planck mass and the mass of the scalar field, respectively. It is interesting that properly defined specific angular momentum for rotating boson stars is constant in space.
