Compilation of Catalog of Stellar Equatorial Coordinates and B-Magnitudes Using UKRVO Plate Database
Pakuliak, L. K.; Yatsenko, A. I.; Shatokhina, S. V. +6 more
To ensure the rational use of informational resources generated by UkrVO in MAO NASU, a catalog of equatorial coordinates (α, δ) and B-magnitudes of stars was created by using plates obtained during observational campaign named FON (ukr., Photographic Sky Survey). 102 plates with field of view of 8° were processed. Digitization of plates with size…
The Scientific Use of the UKRVO Joint Digital Archive: GRBs Fields, Pluto, and Satellites of Outer Planets
Yizhakevych, O.; Andruk, V.; Pakuliak, L. +6 more
In the framework of UkrVO national project the new methods of plate digital image processing are developed. The photographic material of the UkrVO Joint Digital Archive (JDA - http://gua.db.ukr-vo.org/vo-mao/DB/archivespecial.php) is used for the solution of classic astrometric problem - positional and photometric determinations of objects registe…
Astrometry of χ and H Persei Based on Processing of Digitized Plates of Archive of the Astronomical Institute of the Academy of Sciences of the Republic of Uzbekistan
Ehgamberdiev, Sh. A.; Muminov, M. M.; Yuldoshev, Q. X. +3 more
Work is done with Epson Expression 10000XL scanner of Astronomical Institute (AI) of the Academy of Sciences of Uzbekistan. The plates were exposed with the Normal astrograph (D/F = 330mm / 3467mm, M = 59.56"/mm). The digitization of plates with (16x16) cm in size was made with resolution of 1200 dpi (1px = 1.25"). Test research was done using pla…
Explosive Nucleosynthesis at Strong Stellar Magnetization
Kondratyev, V. N.; Korovina, Yu. V.
Synthesis of iron group nuclides is considered for the ultra-magnetized astrophysical plasma in supernovae. Magnetic modification of nuclear structure is shown to shift maximum of nucleosynthesis products towards smaller mass numbers enhancing titanium yield. The results are corroborated with an excess of 44Ti revealed from the INTEGRAL…
