Boris Vasilyevich Kukarkin

Boris Vasilievich Kukarkin ( Russian Борис Васильевич Кукаркин ; born October 30 ^{. Jul} / 12. November 1909 ^greg. In Nizhny Novgorod ; † 15. September 1977 in Moscow ) was a Russian astronomer and university teachers .

Life

Kukarkin was the third child of the university professor of Russian literature Vasily Wassiljewitsch Kukarkin, who was arrested in 1937 and died in a labor camp in 1938 , and his wife Jelena Alexandrovna née Allendorf. After attending school and doing independent training, at the age of eighteen he became head of the observatory of the Nizhny Novgorod Society of Friends of Physics and Astronomy and remained so until 1931. In 1928 he discovered the connection between the period and the spectral class of the variable stars . In the same year he initiated the founding of the Russian bulletin Variable Stars and remained its editor in charge until his death. He was a corresponding member of the Russian Society of Friends of Space .

In 1931, Kukarkin became an astronomer at the Tashkent Observatory . From 1932 he worked at the Moscow University (MGU). In 1934, together with Pawel Petrowitsch Parenago, he found that in U-Geminorum stars the eruption amplitude correlates with the time interval between the eruptions ( Kukarkin-Parenago relationship ). In 1935, Kukarkin received his doctorate with the entirety of his work without defending a dissertation as a candidate for physical-mathematical sciences . He carried out extensive investigations into the brightness of the Cepheids and their fluctuations. Together with Parenago he cataloged the variable stars with their characteristic properties. This became the basis for the General Catalog of Variable Stars .

During the German-Soviet War he served in the Red Army , where he was promoted to captain of the air force . After the war he was sent to Germany as a member of an officers' group in order to identify scientific systems for possible export to the USSR as reparations . Kukarkin recommended for the 40 cm - astrographs the observatory Sonnenberg , which up to the present in Crimean Astrophysical Observatory of the Sternberg Institute for Astronomy (Gaisch) of the MGU in simeiz is used.

In 1947, Kukarkin defended his doctoral thesis at MGU . In 1951 he was appointed professor at MGU. 1952–1956 he was director of the GAISch. 1956–1960 he headed the department for variable stars at GAISch. From 1960 he headed the chair for stellar astronomy at MGU (from 1965 chair for stellar astronomy and astrometry ) and the department for galaxies at GAISch . He developed the concept of star populations in galaxies that form in galaxies at different times. In addition to the work of Walter Baade , Kukarkin's studies contributed to the acceptance of the concept of the galaxy as a star system with interacting subsystems. He published the results of his detailed investigation of globular clusters as a monograph in 1974 . Another focus of the investigation was the light absorption of the interstellar dust .

From 1949 to 1961, Kukarkin headed the astronomy editorship of the Great Soviet Encyclopedia . He was Chairman of the Variable Stars Commission of the Astronomical Council of the Academy of Sciences of the USSR (since 1956) and President of Commission No. 27 on Variable Stars of the International Astronomical Union (IAU) (1952–1958) and Vice President of the IAU (1955– 1961).

Kukarkin died en route to a meeting of the GAISch Scientific Council. He was buried in the Donskoy cemetery .

Kukarkin's name is the asteroid (1954) Kukarkin .
