The effects of a source structure on the microlensing light curves caused by double stars are investigated. The value of the time delay for the double quasar UM673 (Q0142-100) has been obtained for the fitst time. The problem of the homogeneous circular torus stability is examined. This structure is observed in astrophysical objects of various types. The toroidal structures are shown to be stable on sufficiently large time intervals. Kinematic properties of the Galaxy are obtained with use of the absolute proper motions of stars from the XPM catalogue, which can be the initial data for recovering the total matter distribution - both luminous and dark one.
