DOI: https://doi.org/10.18524/1810-4215.2017.30.114270 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 equations with the SF potentials that are negative for some SF values in order to consider black hole configurations. We show that, for some parameters of the family, there can exist two disconnected regions of stable circular orbits around the configuration. Such regions can exist both for black hole and fornaked singularities.

DOI: https://doi.org/10.18524/1810-4215.2017.30.114335 Influence of magnetorotational instabilities in astrophysical plasma at supernova explosion on synthesis of chemical elements is investigated. At field strength less than 10 teratesla nuclear magnetic susceptibility exhibits linear regime with enhanced nuclear binding energy for open shell nuclei. Effects of ultra-strong nuclear magnetization are demonstrated to enhance the portion of titanium product. The relation to an excess of titanium isotopes revealed from the Integral mission data and galactic chemical evolution is discussed.

DOI: https://doi.org/10.18524/1810-4215.2017.30.117655 This paper describes the Ukrainian database of long-term photometric observations of resident space objects (RSO). For the purpose of using this database for the outer space monitoring and space situational awareness (SSA) the open internet resource has been developed. The paper shows examples of using the Atlas of light curves of RSO's for analyzing the state of rotation around the center of mass of several active and non-functioning satellites in orbit.

DOI: https://doi.org/10.18524/1810-4215.2017.30.117154 We derived LTE zirconium abundance in a sample of 81 giant stars in dwarf spheroidal Fornax galaxy. The LTE synthesis was used for this aim. We obtained the lower Zr abundance in Fornax galaxy comparing to the relevant value in the thick/thin disc of the Milky Way. We note that this result may be affected by the NLTE effects that decrease the real zirconium abundance.
