Biography:
She was born on January 15, 1938 in Voronezh city of Shostka district of Sumy region of Ukrainian SSR.
In 1955 she graduated from high school in Tambov with a silver medal.
After graduating from M. V. Lomonosov Moscow State University in 1960, which she entered in 1955, she was enrolled in the Crimean station of the P. K. Sternberg State Astronomical Institute (according to other sources from 1960 to 1961 worked as an engineer in the Military Unit №25840 in the Bolshevo village of Korolyov district of Moscow region), where she went from laboratory assistant to senior researcher, in recent years worked in the Department of Physics of Emission Stars and Galaxies (since 1961 to 1966 laboratory assistant, then a junior researcher, then a researcher in 1986-1990, and then a senior researcher).
From 1966 to 1969 she was a graduate student at the Faculty of Physics of the MV Lomonosov Moscow State University and the P. K. Sternberg State Astronomical Institute.
She worked as an observer at various telescopes at the P. K. Sternberg State Astronomical Institute and the Crimean Astrophysical Observatory and other observatories. During 1969-1980 she took an active part in the creation of the well-known spectrophotometric catalog of bright stars of the P. K. Sternberg State Astronomical Institute.
In 1973 she defended her Ph.D. dissertation, which was devoted to Fabry-Perot interferometry of some galactic HII regions. The title of the dissertation is formulated as follows: "Interference and spectral study of gas nebulae". Doctor of Physical and Mathematical Sciences P. V. Shcheglov was her research supervisor.
She died on July 21, 2017.
She was an expert in extragalactic astronomy. She conducted comprehensive studies of the active nuclei of galaxies, blazars, for many years she conducted photometric monitoring of these and other extragalactic objects. She observed nebulae and stars. She has published 215 scientific papers as an author or co-author.
Since 1961 to 1965 she conducted spectral observations of planetary nebulae according to the program of Professor B. A. Vorontsov-Velyaminov, and also studied the New Hercules. Until 1972, she studied the velocity field in nebulae according to observations with the Fabry-Perot standard; according to spectral observations of gas nebulae determined physical parameters: temperature, density and more.
During 1969-1984 she studied the distribution of energy in the spectra of bright stars and created a network of secondary spectral standards. The result of this work is the publication of the handbook "Spectrophotometry of bright stars" (edited by I. M. Glushneva), whose materials were used to determine the effective temperature, acceleration of gravity, radii of stars. According to these observations, VT Doroshenko conducted research on variable stars CygX-1, X Per, N Cyg 1975, 5 Shield, Plyons.
Since 1978, together with V. Yu. Terebizh was searching for the active nuclei of galaxies according to the list of objects with high surface brightness compiled by M. A. Arakelyan.
Observations of the active nuclei of galaxies on telescopes of the P. K. Sternberg State Astronomical Institute and the Crimean Astrophysical Observatory allowed to obtain long-term (30 years and more) unique series of photometric data on Seifert galaxies, indicating the nature of flash activity, delays. In collaboration with the Crimean Astrophysical Observatory, it conducted spectral studies on the nature of changes in the profiles of emission lines of Seifert galaxies and the time delay of changes in emission lines on changes in continuous radiation, as well as determining the mass of central black holes. These works showed evidence of various (chaotic, virial, radial) movements of gas in the field of education of broad lines in Seifert galaxies.
She created a catalog of 940 faint stars (13-17 magnitudes in the V band), measured with an accuracy of 0.01 magnitudes, on the outskirts of more than a hundred Seifert galaxies, quasars and blazars.
These works were used by staff of various observatories. Many variables were identified among the studied stars, some of which were studied in detail.
She has participated in many international multiwave cooperations on observations of active galaxy nuclei, contributing to his observations in the optical field.
