The Re-Processing Results of Photographic Observations of Asteroids with GAIA Catalog at the Mao Nas of Ukraine
Andruk, V. M.; Shatokhina, S. V.; Kazantseva, L. V.
In total, about 4,500 asteroid po-sitions were determined from photographic observations conducted at the MAO NAS of Ukraine in 1952-1996. These are the early positions of the selected minor planets, mostly bright, the observations of which were initiated by the founders of the ORBITA observational program and were made in 1952-1986. The second la…
Material of Cometary Nuclei and Asteroids can BE Studied in the Earth's Orbit
Vidmachenko, A. P.; Steklov, A. F.
The Solar system is formed from a primary gas-dust cloud. Asteroids and cometary nuclei are made of the same substance. Therefore, the study of their debris will help determine their properties. It is best to investigate the substance of meteoroids in the laboratory. The presence of radioactive chemical elements in meteorites provides important in…
Spectroscopic Investigations of Galactic Clusters with Associated Cepheid Variables. III. Collinder 394 and BB SGR
Kniazev, A. Yu.; Miroshnichenko, A. S.; Mishenina, T. V. +4 more
We present the results of a spectroscopic and photometric investigation of 20 objects from the open cluster Collinder 394, which contains the Cepheid BB Sgr. Besides the Cepheid, we studied tree K-giants, four B-giants, and twelve B-A-F main sequence stars. Radial velocities (RV), v sin i, Teff, log g, were determined using spectroscopi…
Probabilities of Physical Link Between the Components of the Selected Multiple Systems from WDS Catalog
Protsyuk, Yu. I.; Maigurova, N. V.
Astrometric CCD observations of visual components of double and multiple stars were performed using the RI MAO Axial Meridian Circle (AMC) with new Apogee Alta AI-F8300 CCD camera mounted at the telescope in 2018. Observations were carried out automatically in driftscan mode using a standard R filter. Objects for observational program were selecte…
New Astrometric Reduction of the Supercosmos Plate Archive: First Results
Andruk, V. M.; Akhmetov, V. S.; Protsyuk, Yu. I. +2 more
The arrivals of the new more accuracy reference catalogs and development of new methods and approaches for reduction astrometric data give the new life for photographic plates archives. Gaia DR2 is not only a giant step in the astrometric accuracy allowing to measure new objects it also provides plates archives observed in the past with modern acc…
On the Fon Astroplate Project Accomplishment
Ehgamberdiev, Sh. A.; Andruk, V. M.; Pakuliak, L. K. +10 more
The plan of the photographic survey of the northern sky (FON) was proposed in 1976 in Golosiiv observatory (now MAO NAS of Ukraine) by I. Kolchinsky and A. Onegina. The final project of the Compiled FONAC catalog (FON Astrographic Catalog) is based on the digital data of photographic plates exposed at four observatories. They are MAO NAS of Ukrain…
