Реферат: В статье установлено свойство конформного отображения геодинамических структур на земной поверхности Тянь-Шаня через геометрический рисунок, оконтуренный точками с однозначным гравитационным потенциалом. На основе этого процессы, происходящие в пространственных образах, формируют дополнительные замкнутые внешние моменты движения на земной поверхности. Кроме того, в Тянь-Шане обозначены следы двух параллельных осей планеты, обеспечивающих трансформацию гравитационной энергии: в северном полушарии за счет вращения Земли, а в южном за счет перемещения масс. Такое деление вносит качественно новый результат в интерпретацию механизма равновесия планеты и причин возникновения землетрясений.
Partial-wave analysis for elastic pC scattering at astrophysical energies
Реферат: A standard partial-wave analysis was performed on the basis of known measurements of differential cross sections for elastic pC scattering at energies in the range 250-750 keV. This analysis revealed that, in the energy range being considered, it is sufficient to take into account the S[1] wave alone. A potential for the triplet S[1]-wave state of the pC system in the region of the JpT=1{-1} resonance at 0.55 MeV was constructed on the basis of the phase shifts obtained from the aforementioned partial-wave analysis.
Astrophysical S-factor for the radiative-capture reaction pC ->N[gamma]
Реферат: The possibility of describing experimental data on the astrophysical S factor for radiative proton capture on a C nucleus at energies in the range 0.03-0.8 MeV is considered within the potential cluster model involving forbidden states. It is shown that the energy dependence of this astrophysical S factor can be reasonably explained on the basis of the E1 transition to the P[1]-wave bound state of the N nucleus in the pC channel from the S[1] wave of pC scattering in the resonance energy region around 0.55 MeV in the laboratory frame.
Реферат: The possibility of description of experimental data on the astrophysical S-factor of radiative рC capture within the framework of the potential cluster model with forbidden states is analyzed at energies in the range 0.03-0.8 MeV. It is demonstrated that the behavior of the astrophysical S-factor can be explained based on the Е1-transition to the bound P[1] state of the (14}N nucleus in the рС channel from the S[1] wave of рС scattering at resonant energy of 0.55 MeV (l.s.).

Показано, что используемая модель способна правильно передать поведение экспериментальных данных при энергиях от 10 мэВ (10{-2} эВ) до 15 МэВ.
Реферат: На основе известных экспериментальных измерений дифференциальных сечений упругого nС-рассеяния в области углов 20-150 град для восьми угловых значений выполнен стандартный фазовый анализ при астрофизических энергиях 50-1040 кэВ. Полученные фазы упругого рассеяния полностью согласуются с результатами потенциальных расчетов и спектрами уровней ядра С при низких энергиях.

Реферат: Astrophysical S-factors of radiative capture reactions on light nuclei have been calculated in a two-cluster potential model, taking into account the separation of orbital states by the use of Young schemes. The local two-body potentials describing the interaction of the clusters were determined by fitting scattering data and properties of bound states. The many-body character of the problem is approximatively accounted for by Pauli forbidden states. An important feature of the approach is the consideration of the dependence of the interaction potential between the clusters on the orbital Young schemes, which determine the permutation symmetry of the nucleon system. Proton capture on H, Li, Li, C and C was analyzed in this approach. Experimental data at low energies were described reasonably well when the phase shifts for cluster-cluster scattering, extracted from precise data, were used. This shows that decreasing the experimental error on differential elastic scattering cross-sections of light nuclei at astrophysical energies is very important also to allow a more accurate phase shift analysis. A future increase in precision will allow more definite conclusions regarding the reaction mechanisms and astrophysical conditions of thermonuclear reactions.

Реферат: The phase shift analysis, done on the basis of the known measurements of the differential cross-sections of the рС elastic scattering at the energy range 250-750 keV, shows that it is enough to take into account only S[1] wave in the considered energy region. The potential for the triplet S[1] state in рС system at the resonance energy 0.55 MeV corresponding to quantum numbers J{пи}T = 1-1 as well as the potential for the Р[1] bound state of N were constructed on the basis of the obtained scattering phase shifts. The possibility to describe the experimental data of the astrophysical S-factor of the рС radiative capture at the energies 0.03-0.8 MeV was considered within the potential cluster model with the forbidden states. It was shown that we properly succeed in explanation of the energy behavior of the astrophysical S-factor for the рС radiative capture at the resonance energy range 0.55 MeV (laboratory system).

Реферат: The results of the spectral and photometric observations of the object MWC 560. These results were obtained just before and after the last giant flash of the object , which took place on February, 2011. The profiles of absorption components of H[beta] and H[alfa], which are formed in the jet, are presented. Such results are important for study of the jet\' dynamic and development.
Apsidal motion of the eccentric eclipsing binary GSC 4487-0347
Реферат: The eclipsing variable star GSC 4487-0347 is a recently discovered binary system. We carried out observations of the eclipsing binary using a CCD-array in 2009, 2011 at the Tien-Shan Observatory. The B, V, R magnitudes were measured and the spectral range of components were estimated. The photometric elements were derived from the light curve. We found the apsidal period is U=160+-6 years.
