Using the Outskirts of Galaxy Clusters to Determine Their Mass Accretion Rate

open access: yesGalaxies, 2016
We explore the possibility of using the external regions of galaxy clusters to measure their mass accretion rate (MAR). The main goal is to provide a method to observationally investigate the growth of structures on the nonlinear scales of galaxy ...

Computation of asteroid proper elements: Recent advances [PDF]

open access: yesSerbian Astronomical Journal, 2017
The recent advances in computation of asteroid proper elements are briefly reviewed. Although not representing real breakthroughs in computation and stability assessment of proper elements, these advances can still be considered as important improvements

Interstellar Reddening Effect on the Age Dating of Population II Stars

open access: yesGalaxies, 2017
The age measurement of the stellar halo component of the Galaxy is based mainly on the comparison of the main sequence turn-off luminosity of the globular cluster (GC) stars with theoretical isochrones.

On the stability of an infinite cylinder having anisotropic velocity distribution

open access: yesВісник Астрономічної школи, 2003
The stability is studied with respect to longitudinal perturbations of an infinite cylinder homogeneous along z axis. The problem is reduced to the one-dimensional one by the proper choice of the model.

From pulsations of the Sun to the wave nature of the planetary system structurization

open access: yesВісник Астрономічної школи, 2011
Investigation of the planetary distances ordering in the Solar system is initiated by the pulsations of the Sun with a period P_0 = 160 minutes, as it was found [1] that kinematics of the planetary system can be determined with “spatial scale” L_0 = c ...

Problems of the dynamics and the origin of comets

open access: yesВісник Астрономічної школи, 2000
We consider some problems concerning the dynamics of comets far from the Sun. In this connection an estimate for the different hypotheses of the comet origin is given.
