Biography:

She was born in 1948 in the Barabinsk city of Novosibirsk region of the Russian SFSR.

In 1970, she graduated from the A. M. Gorky Ural Order of the Red Banner of Labor State University.

In 1981, she defended her PhD thesis "Absolute proper motions of stars and spatio-kinematic characteristics of centroids in the Main Meridian Crossing of the Galaxy" at the Main Astronomical Observatory of the Academy of Sciences of the Ukrainian SSR.

In 1990, she defended her doctoral thesis "Astronomical studies of the main meridian crossing of the Galaxy" at the Main Astronomical Observatory of the Academy of Sciences of the Ukrainian SSR.

He works as a leading researcher at the Main Astronomical Observatory of the National Academy of Sciences of Ukraine in the Department of Physics of Stars and Galaxies.

She created a consolidated catalog of astronomical data of 2.5 million stars of the entire sky. The catalog contains equatorial coordinates, proper motions, trigonometric parallaxes and photometric data of stars.

Together with S.P. Rybko, A.I. Yatsenko according to the data of the series of special star catalogs created in the department, she conducted a study of the kinematics of the Galaxy and its individual components.

Using the catalog, 2MAst she confirmed reality and determined parameters for 3206 cluster-like objects, namely: complex probability of stars belonging to a cluster, center coordinates, angular size, proper motion, distance, color excess, age, tidal parameters, radial velocity. The completeness of the sample is 2 kps and includes the spiral arms of Perseus and Sagittarius-Kyle. The galaxy is covered from the center to the outermost outskirts. The age range of 1 — 12.6 billion years covers the entire time interval of the Galaxy's existence. No gap in evolutionary parameters between scattered and spherical clusters was found, which indicates the genetic unity of these two subsystems.

In 2012, together with P. M. Fedorov, she became a laureate of the E. P. Fedorov Prize of the National Academy of Sciences of Ukraine for the series of works "Stellar data catalogs as tools for astronomical research".

In cooperation with O.E. Piskunov and a group of German colleagues N.V. Kharchenko made a breakthrough in the field of research on the population of scattered clusters of the Galaxy. In the course of the large-scale survey, a comprehensive census of galactic clusters was carried out, including both known and new previously unknown objects. As a result of this survey, the number of galactic scattered clusters studied in detail has doubled (from 1500 to 3000). For each of them, a complete multifactorial set of parameters is determined, including the complex probability of stars belonging to a cluster, center coordinates, angular size, proper motion, distance, excess light, age, and inflow parameters. Based on these data, the composition, structure and evolution of the Galactic population of scattered clusters were studied. The evolution of the integral parameters of these objects was studied. It is shown that the observed cluster parameters cannot be adequately described by models with a continuous NFM and require assumptions about the discreteness of the NFM. This leads to spikes in cluster integral luminosities and colors at times when the most massive members flare as red supergiants or giants and then die out just as quickly, allowing the observed statistics of red giant flares to be used to estimate lower stellar masses in Galactic clusters.
