We study brightness variations in the double lensed quasar UM673 (Q0142-100) with the aim of measuring the time delay between its two images. Methods.. We analyzed the V, R and I-band light curves of the A and B images of UM673, which cover ten obser

The problem of nonlinear stability of a circular cylinder and Maclauren disk with respect to non-radial oscillations, which give to the stellar system an elliptical form and maintain the space density constant in the disturbed state, is discussed. Ti

By the method of lagrangian coordinates the non-linear radial oscillations of self-consistent models – the Camm’s sphere, the Maclaurin’s disc and the cylinder – are studied. In all these models the velocity diagram is anisotropic. It is foun

Two interesting properties of the Camm’s equilibrium model are given. The analytical exact form of its autonomous oscillations associated with volume perturbations is found by the Jacobi polynomials. The total stability of the model with respect to

In view of the absence of a satisfactory solution to the globular cluster (GC) classification problem, we have searched for a physical parameter that admits of the GC classification and finding empirical dependences on observed physical characteristi

In this paper, we study the strong non-stationary stochastic processes that take place in the phase space of self-gravitating systems at the earlier non-stationary stage of their evolution. The numerical calculations of the compulsive phase mixing pr

We study strongly non-stationary stochastic processes which take place in the phase space of disk-like self-gravitating systems at the early stage of their evolution. Numerical calculations were carried out based on the model of chaotic effects accor

Our composite catalog of globular cluster systems (GCS), which was studied in part I [1] of this paper , has been substantially extended because of a lack of data in it for use in searches for empirical relationships between the physical parameters o
