HIP 13962 – THE POSSIBLE FORMER MEMBER OF BINARY SYSTEM WITH SUPERNOVA
Journal Title: Odessa Astronomical Publications - Year 2016, Vol 29, Issue
Abstract
The run away supergiant star HIP13962 (spectral type G0Ia) was recently pointed as a possible former binary companion of young pulsar PSRJ0826+2637. The spectraof HIP13962 wereo btained in Haute-Provence observatory (France), in Bohuynsan observatory (Korea), and also in NARIT (Thailand) with1.9, 1.8, and 2.4 meter telescopes respectively. The spectra were obtained in 1995, 2003, 2005, 2014, and 2015. Significant variations of the spectrum are detected. The cores of strong lines show complicated structure, the brightness of the star is variable. The cycles of photometric variations have been changed. We analyzed the spectral observations and present the preliminarychemical composition for elements from iron to lead. The abundance pattern cannot be fitted by solar system r&s process abundance distribution.

EFFECTIVE TEMPERATURE AND RADIAL VELOCITY OF THE SMALL AMPLITUDE CEPHEID POLARIS (alpha UMi) IN 2015
We present the results of an analysis of 21 spectra of alpha UMi (Polaris) obtained in September – December 2015. Frequency analysis shows an increase of the pulsation period up to 8.6 min in comparison to the 2007 obser...

We will use Geroch-Held-Penrose formalism for decoupling of quantity dΨ4, which is responsible for tensorial perturbations, in Bianchi equations. We will concentrate on the case, where we eliminate the source terms.
