Spiral galaxies are considered as static, spherically symmetric dark matter configurations (DMC), described by Tolman's type VII solutions with vanishing surface density. In this model it is possible to obtain flat, slightly rising and even declining rotation curves. Star and gas clouds are considered as trapped luminous nonzero restmass particles. They move along their appropriate trajectories provided by the space-time curvature due to DMC.
