Main actors in astronomy research in the country  There are 7 Research Institutes in the structure of the National Academy of Sciences of Ukraine (NAS of Ukraine), 2 Research Institutes in the structure of the Ministry of Education and Science, Youth and Sport of Ukraine (MESYS of Ukraine); 15 astronomical observatories and Departments in the structure of the Universities of the MESYS of Ukraine; 1 Private Astronomical Observatory play a main role in the development and teaching Astronomy in Ukraine.
The XPM Catalog  Absolute proper motions of 280 million stars distributed all over the sky without gaps in the magnitude range 10m < V <20m on the basis of combined data from 2MASS and USNO-A2.0 catalogues.
MAO NASU Plate Archive   Digital archive of MAO NAS of Ukraine (GPA) comprises data of about 26 thousands of direct photographic plates, obtained with 14 instruments in 9 observational sites, and more than 2000 digital images of different resolution available via GPA search pages.
Mykolaiv AO Plate Archive   Digital archive of Mykolaiv Aastronomical Observatory (MykAO) includes astronomical data obtained during observations with photo plates and CCD frames. The digitization of the archive is near its completion. Digitized images are available via a web browser and Aladin.
AO LNU Plate Archive   Astronomical Observatory of Lviv National University (AO LNU) is the owner of valuable archive that stores approximately 8 000 of photographic plates from 1939, including nearly 6 000 direct images of the northern sky. The archive is partly digitized and images are available via the joint search pages of AO LNU and MAO NASU.
IRA UTR-2 catalogue of RS   The very-low frequency sky survey of discrete sources has been obtained in the Institute of Radio Astronomy of the Ukrainian National Academy of Sciences (Kharkov, Ukraine) with the UTR-2 radio telescope at a number of the lowest frequencies used in contemporary radio astronomy within the range from 10 to 25 MHz.
Mykolaiv AO stellar catalogues   27 astrometric stellar catalogues of Mykolaiv Aastronomical Observatory (MykAO) in VOTable format are available for downloading
AO KNU Historic Plate Archive   AO KNU glass collection contains about 20 thousand photographic plates. Historical part of the archive was received during 1898-1946 and now is being digitized.

VOPlot v1.8 Beta 
VOPlot v1.8Beta includes many enhancements and bug fixes. To name a few v1.8Beta supports multi-grid plots for 2D Scatter-Plot which allows the user to have multiple plots having grid size from 1x1 to 3x3 in a single window. Paginated view is added to see data in tabular format which allows user to navigate systematically. Provision to label Lat/Long lines is also added. Users can now plot a cumulative histogram for all histogram types. VOPlot 1.8Beta shows the metadata of a FITS file instantaneously while the actual loading happens in background. VOPlot v1.8Beta also provides better handling of "faulty data" while parsing an ASCII file.

Place of birth: Yashnyky village, Lokhvytskyi District, Poltava Province, Russian Empire

Studied in: Imperial Kharkiv University, Kharkiv province, Russian Empire (since 1999 V. N. Karazin Kharkiv National University, Kharkiv region, Ukraine) ();

Key interests: mathematisc, astronomy. ScD Thesis: On special solutions of differential equations (1850 ); ScD Thesis: About the curvature of surfaces (1851 );


He was born on June 14 according to the Julian calendar (or 26 according to the Gregorian calendar) in 1814 in the Yashniki village of the Lohvytsky District of the Poltava Governorate of the Russian Empire (now Lokhvytskyi District of the Poltava Region of Ukraine) in the family of a nobleman of the Poltava Governorate.

He was left an orphan early. The older brother took Amos to Kharkiv City and sent him to a regional school there. After graduating from it, he entered the Slobid-Ukrainian gymnasium, where in 1831 he successfully completed the science course. After that, he entered the medical faculty of the Imperial Kharkiv University, but after 4 years he transferred to the physics and mathematics faculty, where he graduated with a candidate's degree.

After graduating from the university, Dyachenko was appointed in 1840 to perform the duties of a mathematics teacher at the Kamianets-Podilskyi Male Gymnasium, and in 1843 he was confirmed in this position. In 1846, he was transferred to the St. Vladimir Imperial Kyiv University to perform the duties of an adjunct professor of the department of pure and applied mathematics.

In 1849, Amos Andriyovych was given the rank of court adviser.

In 1850, Dyachenko, who passed the exams and submitted his thesis "On special solutions of differential equations", was awarded a master's degree, and in 1851, for his work "On the curvature of surfaces", he was awarded the degree of doctor of mathematics and astronomy. Both dissertations were not printed.

In 1852, Amos Andriyovych was approved as an extraordinary professor of the department of applied mathematics of the university. Dyachenko read statics and dynamics for 4 hours a week, guided by the works of Lagrange, Poisson and Duhamel. In addition, he read sketch geometry for 3 hours a week, following the works of Leroy and Vallée. In 1847 and 1848, he read algebraic analysis and the theory of equations for 4 hours a week, relying on the works of Fourier, Cauchy, Lagrange and Drobysh.

By the decree of the Heraldry of June 11, 1852, Amos Dyachenko was approved in the nobility, he was included in the second part of the genealogical book of the Poltava province.

He died on the 7th of the Julian calendar (or the 19th of the Gregorian calendar) on August 1852 in the Kyiv city from tuberculosis.

He did not leave behind any printed works.
