Biography:
She was born January 8, 1951 in Novooleksiyivka station of the Henichesk district of the Kherson region of Ukrainian SSR.
In 1974 she graduated from the Faculty of Mechanics and Mathematics of the V.V. Kuibyshev Tomsk State University, where she joined in 1969.
Officer of the Crimean Astrophysical Observatory since 1975. During 2014-2017 (according to other data since 2015) she worked as the head of the "Double Stars" laboratory at the Department of Physics of the Stars, and since 2018 he has been a leading research fellow at the Observatory's Physics Department.
Together with Prokofieva V. V., Bondar N.I., Mayer V.A., Abramenko O. M. and Sharipova L. M. developed a television set for photometric and spectrophometric studies of stars, which was set at 0.5-m meniscus Telescope MTM-500 ((F / 13) at the Crimean Astrophysical Observatory.
In 1993 she defended his Ph.D. thesis "Photometric Investigations of Some Magnetic and X-ray New" at the National Academy of Sciences of Ukraine. V. V. Prokofieva was her scientific director.
In 2010 she defended his doctoral dissertation "Cataclysmic variables and related binary stars with low component mass ratios" in the specialty "astrophysics, radio astronomy".
Since 2018 she has worked part-time as a professor at the basic department of astrophysics and space physics at the Physical-Technical Institute of the V. I. Vernadsky Crimean Federal University.
She is the representative of the academic school of Academician A.B. Severniy.
Since 2018 astronomer is a member of the editorial board of the scientific journal "Astrophysics".
In 2009, she became a laureate of the M.P. Barabashov Prize of the National Academy of Sciences of Ukraine. In 2011 she was awarded the honorary title "Honored Worker of Science and Technology of Autonomous Republic of Crimea".
The main direction of scientific research is photometric study of cataclysmic variable stars and related objects. Until 1998, research was conducted using high-sensitivity television tubes as light-receiving equipment, and then with the help of charge-coupled devices (CCD). In the 1980s and 1990s, she worked with Spanish, British, and Russian colleagues on low-mass X-ray binary systems involving black holes. In particular, V518 Per together with A. Shlyapnikov, a graduate student of the Crimean Astrophysical Observatory, and A. Castro-Tirado, a Spanish colleague, discovered an optical component for the first time, which later made it possible to study this object in different spectrum ranges; an orbital period was detected in QZ Vul during the outbreak. Investigating the photometric behavior of the magnetic New Swan in 1975 on a scale of more than 10 years, found asynchronous orbital-axial rotation of the white dwarf and its rapid synchronization. Estimated synchronization time and showed its nonlinear nature, consistent with the theoretical prophecy of I. Andronov in 1987 and J. Katz in 1991 that synchronization with such features may be due to the action of a strong magnetic field of the white dwarf, and the interaction its magnetospheres with "ultraviolet wind" from the secondary component.
In another asynchronous BY Cam polar, the geometry of accretion at the poles of the white dwarf was determined depending on the orientation of the magnetic field of the dipole + quadrupole type and it was found that the object is at the stage of slow orbital-axial synchronization.
As a result of studies of about two dozen dwarf new SU UMa types, non-radial pulsations of the white dwarf that accretion in the EZ Lyn system were detected for the first time, their evolution was studied and it was shown that the white dwarf entered the instability band twice in ten years; in dwarf new MN Dra and 1RXS J0038 precession of the accretion disk node line was detected for the first time. The work was carried out in collaboration with colleagues from the Crimean Astrophysical Observatory, the P. K. Sternberg State Astronomical Institute, the Astronomical Institute of the Slovak Academy of Sciences, and the University of Kyoto city.
E. P. Pavlenko discovered the effect of a quadrupole magnetic field on a component in an old binary system.
The number of her scientific publications is about 300.
