• Has been processed an effective way of stellar densities’ calculations, known in publications as the Vashakidze–Oort Method.
  • Mikheil Vashakidze established the nature of Crab Nebula. It was proved that, even in the visible range, the nebula’s radiation is originated not by heat, but by the synchrotron mechanism.
  • Was published the Atlas of the Galactic dark nebulae (Author J. Khavtasi)
  • Evgeni Kharadze and Ramze Bartaia processed the Abastumani System of Classification for specters taken on 70-cm meniscus telescope.
  • One of the craters on the dark side of the Moon was named after Mikheil Vashakidze in 1970.
  • Rolan Kiladze noticed an atmosphere around the plane Mercury.
  • From 20th of February 1976 to 20th of February 1977 study of an astro-climate of Mt Kanobili was held under the leadership of Guram Salukvadze and with employment of modern methodology and especially designed device (Two-Rayed Tool).
  • Guram Salukvadze and the group of scientists from The Sternberg Astronomical Institute researched of microclimate at the inner space of a telescope dome for the first time. Quantitatively assessed its influence on the quality of stellar images.
  • Spectral classification of more than 200 000 faint stars took place in the Observatory. Extensive catalogues of spectral and luminosity classes have been published (authors E. Kharadze, R. Bartaia, Chargeishvili, N. Kalandadze, M. Metreveli at all).
  • Kiladze predicted existence of Pluto’s satellite.
  • Guram Salukvadze developed the criteria for determination of Trapezium type multiple stars from the number of binary and multiple systems. First complete catalogues of Trapezium type multiple stars was created based on index-catalogue of binary stars. Based on observational data Guram Salukvadze proved Viktor Ambartsumian’s theoretical propose on collective nature of stellar genesis.
  • The small asteroid 1247 discovered by the Danish scientist R. West was named after Eugeni Kharadze.
  • The Polarimetric Atlas of the Moon. Authors P. Japiashvili, A.N. Korol.
  • Based on own observational materials and observational data of worldwide databases Guram Salukvadze studied the kinematics of Trapezium type multiple stars. The results are proving that majority of Trapezium type multiple stars are unstable objects and their age does not exceed 10 million years. Guram Salukvadze revealed 120 Trapezium type multiple stars majority from which (80) are physical.
  • The small asteroid 4737 discovered by N. Chernikh, Crimean Astrophysical Observatory, was named after Rolan Kiladze in May
  • In the result of electro-photometric observations in six-colored photometric system Guram Salukvadze and Gia Javakhishvili established that great majority of Trapezium type multiple stars, main star of which belongs to OB-2 spectral class, are physical systems. Masses of components several times exceed the solar mass and age of 70 from them is less than 4 million years. Last fact proves that the systems are one of youngest systems in the Galaxy.
  • Through its history, The Abastumani Observatory sent up to twenty scientific expeditions to observe total solar eclipses. The expeditions where sent to different countries of four continents of Earth, and travelled up to 300 000 kilometers in sum. The significant results were gathered about the structure and nature of solar corona. (M. Vashaklidze, Ts. Khetsuriuani, V. Kulijanishvili, Salukvadze, R. Kiladze, E. Khutsishvili, M. Gigolashvili, D. Japaridze and others).
  • Researchers of Abastumani Observatory published more than 4000 scientific articles. Been published 77 issues of collections of scientific works ‘The Bulletin of Abastumani Astrophysical Observatory’.
  • Works of scientists from the observatory been awarded with: the State Prize of USSR (R. Kiladze); Fyodor Bredikhin Prize (V. Japiashvili, A. Korol); The Comet Medal of the Astronomical Society of the Pacific (G. Tevzadze), the State Prize of the Republic of Georgia (J. Lominadze, G. Chagelishvili, R. Chanishvili, Rogava).


Following new celestial objects were discovered in the observatory:

  • 1942 G. Tevzadze discovered two new comets;
  • 1948 R. Bartaia discovered a nova;
  • 1958-1961 Sh. Apriamashvili discovered three novae;
  • 1967 G. Salukvadze discovered super-nova;
  • 1971-1989 G. Kimeridze discovered six super-novae;
  • 1980 R. Inasaridze discovered super-nova;
  • 1980-1997 G. Kimeridze and R. Inasaridze discovered two novae and a recurrent nova.


Were revealed: new planetary nebulae; Wolf–Rayet stars; peculiar carbon stars; flare stars and stellar systems.
