Obituary:

On March 3, 2021, Alexander Egorovich Dudorov, Professor, Doctor of Physics and Mathematics, Head of the Department of Theoretical Physics of the Chelyabinsk State University passed away.

Alexander Dudorov graduated from the Kazan State University in 1971 and received an honors degree in Astronomy. After completing his postgraduate studies at the Astronomical Council of the USSR Academy of Sciences, he worked at the Bashkir State University. He worked at the Chelyabinsk State University since 1978. Alexander Egorovich organized the Department of Theoretical Physics at the Chelyabinsk State University and was the head of the department for more than 35 years. From 2005 to 2008 he worked as a dean of the Faculty of Physics.

Professor Dudorov devoted his whole life to science. He was one of the pioneers of theoretical investigations of the magneto-gas-dynamic processes in the interstellar medium and founded a scientific school on the topic of star formation at the Chelyabinsk State University. He was an expert in numerical modeling in astrophysics. Together with colleagues and students, he developed the theory of the fossil magnetic field, in which the magnetic field of young stars is considered as an induction amplified magnetic field of protostellar clouds. He considered various applications of the theory of the fossil magnetic field: the interaction of the magnetic field with convection, the problem of the angular momentum of young stars, the dynamics of the accretion disks of young stars with a large-scale magnetic field, etc.

Alexander Dudorov played a leading role in theoretical and field studies of the Chelyabinsk meteorite. The results of this research have been published in a series of scientific papers and in the monograph "Chelyabinsk Superbolide". For his contribution to the study of the Chelyabinsk meteorite, the International Astronomical Union named the Main Belt Asteroid 8795 (1981 E09) discovered in 1981 as Dudorov.

Alexander Egorovich is the author of over 200 scientific and methodological works. One doctoral and six PhD theses were prepared and defended under his supervision.

He was active in teaching. For many years he gave lectures on the main topics of theoretical physics, taught special courses on cosmical electrodynamics, theoretical astrophysics, and others. He supervised the astrophysical seminar at the Chelyabinsk State University and was actively involved in the popularization of science.

Alexander Dudorov was a versatile and charismatic person. Colleagues and students will always remember his inexhaustible desire to investigate nature in all its manifestations, the sharpness of his mind and sense of humor. Despite his severity, he was a kind and sympathetic person who was always ready to help both colleagues and students. He was an honest and principled person both in science and in life.

Colleagues and friends deeply grieve and express their sincere condolences to the family and friends of Prof. Alexander Dudorov. The memory of him will forever remain in our hearts.
