Stars, Nebulae, Galaxies

All-Union Symposium devoted to V.A. Ambartsumian’s 60th anniversary


September 16-19, 1968, Byurakan, Armenia



The symposium was organized by the Astronomical Council of the Academy of Sciences of USSR, Commission on Physics of Stars and Nebulae and Byurakan Observatory. It was convened in honour of 60th anniversary of Academician V.A. Ambartsumian and devoted to the discussion of research in following three directions:


·         radiation transfer theory

·         physics of non-stable stars and nebulae

·         physics of galaxies


Problems discussed at the symposium concerned those in which a great role belonged to V.A. Ambartsumian, i.e. the problem of light scattering, non-stable stars and active phenomena in galaxies.

About 100 scientists took part in the symposium – representatives of various observatories of the Soviet Union (such as V.V. Sobolev, I.S. Shklovsky, S.B. Pikelner, V.G. Gorbatsky, A.B. Severny, and V.A. Dombrovsky), as well as Poland and DDR.


Byurakan Observatory research workers took an active part in the symposium. They had 11 talks (V.A. Ambartsumian, R.A. Vardanian, E.S. Kazarian, A.T. Kalloghlian, L.V. Mirzoyan, A.G. Nikoghossian, V.S. Oskanian, V.Yu. Terebizh, H.M. Tovmassian, E.Ye. Khachikian, and H.S. Chavushian). Altogether 42 talks were presented.


V.A. Ambartsumian had a report on statistics of flare stars, where showed for the first time that a large amount of dwarf stars in the aggregates are flare ones.
