Vladimir Sergeyevich Imschennik

Vladimir Sergeevich Imschennik ( Russian Владимир Сергеевич Имшенник , English transcription Vladimir Sergeevich Imshennik ; born September 27, 1928 in Debaltseve ) is a Russian theoretical physicist who works on astrophysics , magnetohydrodynamics and plasma physics .

Live and act

In 1932 the Imschennik family moved to Moscow, where he studied physics at the Lomonossow University there until 1951 after the end of the Second World War . After completing his studies, he was involved in theoretical research on the construction of a Soviet hydrogen bomb in the cities of Obninsk and Sneschinsk . Theoretical problems of controlled nuclear fusion remained in the center of his scientific interest during his research life. In 1961 he moved to the Institute for Applied Mathematics of the Academy of Sciences of the USSR , headed by MW Keldysch , where he worked for 18 years. There he mainly researched magnetohydrodynamics ( linear pinch ) and plasma physics. From 1979 he headed the Laboratory for Inertial Fusion at the Institute for Theoretical and Experimental Physics , which later became the Laboratory for Plasma Physics and Astrophysics. Imschennik began working on supernovae , especially supernova explosions and the simulation of supernova light curves as well as neutrino transport in stars, at the Institute for Applied Mathematics . His results formed the basis for the modern hydrodynamic theory of the expansion of supernova shells. The results of his research were essentially confirmed by observations of the 1987A supernova in the Large Magellanic Cloud . Since 1996 he has been head of the department for theoretical astrophysics and problems of thermonuclear physics at the Moscow Institute of Physics and Technology .

In 1982 Imschennik received the State Prize of the USSR . In 2001 he was awarded the Sakharov Gold Medal by the Russian Academy of Sciences . He has been a corresponding member of the academy since 2003.
