Biography:
She was born on January 17, 1928 in Balashov city of Saratov region of the Russian SSR.
In 1950, she graduated from M. V. Lomonosov Moscow State University.
An employee of the Crimean Astrophysical Observatory of the Academy of Sciences of the USSR in Simeiz city since 1952 (according to other data, in 1950 she was sent to work at the Simeiz branch of the Pulkovo observatory).
In 1962 (according to other data, in 1963), she defended her PhD thesis at M.V. Lomonosov Moscow State University "Research of the inner spiral arm of the Galaxy close to the Sun at two sites in the Milky Way."
Together with L.P. Metik, they conducted a spectrophotometric study of the galaxy NGC1275 in the region of its nucleus using the 6th telescope at a scale of 17.5" in mm and an image of 1".
In 1989, she defended her doctoral thesis "Photometric and spectral studies of the central regions and nuclei of normal and peculiar galaxies" at the Byurakan Astrophysical Observatory.
She is a member of the international Eurasian Astronomical Society.
She died on October 8, 2014 in the Naukovy village.
I.I. Pronik was the first assistant of A.B. Severny in observations on the coronagraph in Naukovych, but soon transferred to the department of physics of stars and nebulae and under the leadership of Academician G.A. Shayna studied the stars. She was one of the most active executors of the Shine Plan. In the course of this multi-year work, she classified the spectra and measured the brightness of about 5,400 stars in the constellations Sagittarius and the Eagle, and investigated the spatial distribution of density in the interstellar medium, determining the distance and interstellar absorption on the way to each star. A large part of these results was included in her PhD thesis. Many years later, I.I. Pronik carefully summed up the extensive research of the structure of the Galaxy, carried out according to the Shain Plan by Soviet scientists in the 1950s and 1960s, and in a number of publications restored the priority of G.A. Shain in the experimental substantiation of the concept of star formation from a diffuse medium, a concept that became generally accepted only after the discovery in the 1970s of giant molecular clouds.
In the last four decades, the main research direction of I.I. Pronik astronomy became a penetration. In the course of these studies, she received and analyzed a large amount of data from observations made by her with the help of the Shain telescope in the Crimea and the 6-meter telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences, she studied the morphology, photometric and kinematic features of many active galaxies, and as a result discovered the power relationship radiation in the Na line and color indicators of the central regions of galaxies, found systematic differences in the composition of the stellar population of the central regions and other morphological structures of normal and Seyfert galaxies, discovered blue condensations in the central regions of some active galaxies, which during spectral studies turned out to be massive clusters of hot stars and gas, also discovered emission lines in a number of galaxies with Seyfert nuclei. Some results of I.I. Pronik insights, particularly regarding the variability of active galactic cores at short time intervals, appeared pioneering and met with skepticism, but were later confirmed by many foreign researchers and included in her doctoral dissertation. I.I. Pronik took an active part in the analysis of unique data obtained on the "Astron" space station, which led to the detection of noticeable ultraviolet excesses in the spectra of early morphological types of galaxies.
Author of more than 180 scientific works.
