Biography:
He was born on December 28, 1936 in the Smela city of Kyiv region of the Ukrainian SSR.
In 1954 he graduated from school #15 in Yalta city and entered the astronomical department of the Faculty of Mechanics and Mathematics of M. V. Lomonosov Moscow State University of the Russian SSR, which he graduated in 1959.
After graduation the university he was sent to work at the Crimean Astrophysical Observatory and now climbed the astronomer's career ladder to a leading researcher in the Department of Solar Physics.
In 1975 he defended his dissertation "Structure and dynamics of some solar formations" (Decision of the Council of the Main Astronomical Observatory of the USSR Academy of Sciences (in Pulkovo village) since 31.10.1975).
Since the beginning of his scientific activity he proved to be a skilled experimenter and specialist in the field of optics and telescopes. Participated in laboratory studies of hydrogen plasma in a powerful pulsed discharge to detect the proximity of physical processes in the discharge and solar flares. Participated in the development of the optical system of the Orbital Solar Telescope and optical control. He upgraded the KG-1 coronagraph, which made it possible to obtain images of the Sun with a resolution of 0.8 angular seconds. Under his leadership, a 53-centimeter coronagraph KG-2 was put into operation and surveillance was organized.
The new qualitative level of observations allowed to study fine-grained formations and fine-grained outbreaks. The original method of observing the mustache during a solar eclipse made it possible for the first time to determine the true size and brightness of these nonstationary formations. It was found that the emission of flash tapes is concentrated in fine-grained elements that are not included in the flash process at the same time. The velocity field in the plasma flash volume is also fine-grained and complex: in some elements there are local Doppler motions.
A new direction in the study of the role of thermal and non-thermal processes in flashes has been successfully developed - the study of linear polarization of Hα radiation. Significant polarization of flash and mustache emissions and fine structure of polarized elements were revealed by him.
The structure and strength of the magnetic field in the flash volume of plasma have been studied. Rapid changes in the magnetic fields of the spots during the flash, which correlate with microwave bursts, were detected by him.
Unique spectra of the brightest node of the white flash during the pulse phase were obtained, which showed a number of features previously unknown. Spectral features, as well as model calculations indicate the heating of the deep layers of the flash atmosphere, which is difficult to explain by heating the energy transferred from the corona.
The astronomer is an active participant in the International Solar Research Program, a member of the International Astronomical Union and the European Astronomical Society.
Aston's research interests are solar activity, solar flares, and astronomical optics. He is the author and co-author of 75 scientific publications.
