Life

Parenago, son of a doctor , attended secondary school in Moscow with graduation in 1922 and then studied at Moscow University (MGU) with graduation in 1929. As early as 1927, he worked at the Institute for Astronomy and Geodesy of the MGU.

In 1932 Parenago moved to the Sternberg Institute for Astronomy (GAISch) at MGU. On the basis of the available stellar data , he investigated the structure and development of the Milky Way . Together with Boris Wassiljewitsch Kukarkin , he began to catalog the variable stars with their characteristic properties. This became the basis for the General Catalog of Variable Stars . In the area of ​​the Orion Nebula , the closest star formation region, Parenago observed almost 3000 stars. In 1934, together with Kukarkin, he discovered that in U-Geminorum stars the eruption amplitude correlates with the time interval between the eruptions ( Kukarkin-Parenago relationship ).

From 1934 Parenago worked at the MGU and was the first to hold a lecture on stellar astronomy in the USSR . In 1935 he received his doctorate in physical-mathematical sciences without defending a dissertation . In 1938 he was appointed professor . From 1938 he headed the new chair for stellar astronomy. From 1940 he investigated the light absorption of interstellar dust . He promoted amateur astronomy through publications and lectures .

During the German-Soviet War Parenago served in the Red Army as a meteorology specialist in the air force .

In 1945 Perenago established the existence of the sub - dwarfs, which are located in the Hertzsprung-Russell diagram under the main sequence of dwarf stars . In 1946, together with Kukarkin, he predicted that after the eruption of the Nova T Coronae Borealis an outbreak would be expected again after 60-100 years. In fact, on February 8, 1946, such an outbreak was observed.

In 1953 Parenago was elected a Corresponding Member of the Academy of Sciences of the USSR .

Parenago died after a long illness and was buried in Moscow's Novodevichy Cemetery.

Parenago is named for the asteroid (2484) Parenago and the lunar crater Parenago .
