Biography:
She was born on February 2, 1923 in the Lelyukhovka village of Poltava region of the Ukrainian SSR.
She was a student of A. M. Gorky Kharkiv State University, majoring in "astronomy" of the war years, which combined study with work in the hospital. In 1946 she graduated from A. M. Gorky Kharkiv State University.
After graduation of university she was a graduate student of N. P. Barabashov, graduating in 1949.
After the War, together with Akimov L. A., Evsyukov M. M., Chekirda A. T., Tsvetkova V. S. studied in detail the photometric properties of individual formations of the lunar surface. In 1949, she created a unique photometric catalog of the Moon.
In 1951 she defended her dissertation "Photographic photometry of the lunar surface" at the A. M. Gorky Kharkiv State University.
Its catalog of 176 areas of the lunar surface in the 1950s and 1960s was the main source of information on the reflective properties of the lunar surface not only in the former USSR, but also abroad, particularly in the United States. Also, this catalog was the basis of these works on the choice of places of application of soft landing devices and stations for the collection of lunar soil, which in the USSR were conducted under the leadership of N. P. Barabashov, and later V. I. Ezersky.
She participated in expeditions led by Pluzhnikov V. H. to observe solar eclipses on February 25, 1952 near the Chilistation of Kzilorda region of the then Kazakh SSR and in the Kobeliaky village of Poltava region in June 30, 1954.
At the beginning of the 50s of the XX century she confirmed the effect of strong backscattering on the lunar surface, discovered by N. P. Barabashov in the 20s of the 20th century.
She supervised the supervisory work of the Kharkiv branch №34501 of the International Sun Service during 1962-1964.
In 1952, she performed thorough work on photographic photometry of the lunar surface having processed manually obtained photos of 176 areas on the top of the Moon.
She was an associate professor of astronomy at the A. M. Gorky Kharkiv State University during 1946-1965, working at the University Observatory. She also worked at the G. S. Skovoroda Kharkiv Pedagogical Institute during 1965-1976 (according to other data, she moved to teaching at the institute in 1964) as an associate professor of the physics department.
She died in 1976 (according to other data in 1977).
She is the author of more than 20 scientific papers.
The name of V. A. Fedorets is immortalized in the name of the crater on Venus.
