    DYNAMICAL FRICTION IN THE LOCAL GROUP
    (Astroprint, 2013) Kudinova, A. V.
    In this paper we consider dynamical behavior of the astrophysical objects in the Local Group. The motion of Andromed and The Milky Way is studied. We distinguish two different models: for the first one we do not take into account the influence of the Intra-Group Matter (IGrM), for the second one we take into account the dynamical friction due to the IGrM. We obtained some characteristic IGrM parametres such as particle masses for principle cases of the collision between the giant galaxies and the situation when the merger becomes problematic. We also define the region in the vicinity of our Local Group where the formation of the Hubble Flows starts.

    DYNAMICS OF COSMIC BODIES IN THE OPEN UNIVERSE
    (Astroprint, 2012) Kudinova, A. V.; Eingorn, Maxim V.; Zhuk, Oleksandr I.
    ABSTRACT. As it has been recently demonstrated,the mathematical model with the hyperbolic space(or, in other words, with the negative spatial curvature)is the most appropriate one for describing the inhomogeneous Universe at late stages of its evolution in the framework of the theory of scalar perturbations. In this model we develop a dynamic approach and investigate nonrelativistic motion of two, three and even more cosmic bodies against the cosmological background, perturbed locally by density inhomogeneities (namely, galaxies).

    THE NON-RELATIVISTIC LIMIT OF THE RANDALL-SUNDRUM BRANE WORLD MODEL: SOLUTIONS AND APPLICATIONS
    (Astroprint, 2011) Kudinova, A. V.; Eingorn, Maxim V.; Zhuk, Oleksandr I.
    The non-relativistic limit of the Randall- Sundrum model with a single brane is investigated. Both exact and approximate expressions for the potential of a delta-shaped material source are used, some geometric configurations of the sources are considered. Formulae for the potential energy and the force of the gravitational interaction are derived, including the most important case of two balls. The constraints on the model’s parameter are obtained.
