STABILITY OF STELLAR SYSTEMS ORBITING SGR A*
Journal Title: Odessa Astronomical Publications - Year 2015, Vol 28, Issue 2
Abstract
Path equations of different orbiting objects in the presence of very strong gravitational fields are essential to examine the impact of its gravitational effect on the stability of each system. Implementing an analogous method, used to examine the stability of planetary systems by solving the geodesic deviation equations to obtain a finite value of the magnitude of its corresponding deviation vectors. Thus, in order to know whether a system is stable or not, the solution of corresponding deviation equations may give an indication about the status of the stability for orbiting systems.Accordingly, two questions must be addressed based on the status of stability of stellar objects orbiting super-massive black holes in the galactic center. 1. Would the deviation equations play the same relevant role of orbiting planetary systems for massive spinning objects such as neutron stars or black holes? 2. What type of field theory which describes such a strong gravitational field?

ACCURACY OF MYKOLAIV ASTEROID OBSERVATIONS WITH DIFFERENT REFERENCE CATALOGUES
The results of astrometric reductions of main belt asteroid observations with usage of 3 different reference catalogues are presented. The high precision catalogs CMC15, UCAC4 and GAIA DR1 were used as refer...
THE PROPERTIS OF TIDAL FORCES IN THE KERR METRIC
The expression for the tidal forces of the two relativistic protons at a distance of the order of the Compton wavelength near a rotating black hole is found. The analysis shows that the tidal forces are dependent on the...
THE ELLIPTICITIES OF GALAXIES IN GALAXY CLUSTERS OF DIFFERENT MORPHOLOGICAL TYPE
The distribution of galaxy ellipticities was analyzed for 207 rich PF galaxy clusters found in the Munster Red Sky Survey Galaxy Catalogue. Clusters with BM types from a comparison with the ACO catalogue were also classi...
DISCONNECTED REGIONS OF STABLE CIRCULAR ORBITS IN PRESENCE OF MASSIVE SCALAR FIELD
We study circular orbits around a static spherically symmetric configuration of General Relativity in presence of a nonlinear massive scalar field (SF). The problem deals with a family of solutions to Einstein – SF equatio...
