An astrophysicist from the USA gave a lecture in KazNU

Anatoly Miroshnichenko, Doctor of Physico-Mathematical Sciences, Professor of the Department of Physics and Astronomy at the University of North Carolina at Greensboro (USA), gave a lecture at the Faculty of Physics and Technology of Al-Farabi Kazakh National University.

The lecture was devoted to the topic "The variety of paths of stellar evolution: phenomena related to the interaction of components in binary and multiple systems".

The lecture of the famous scientist became a significant event for the Faculty of Physics and Technology, bringing together professors, scientists, teachers and students of the faculty.

Anatoly Miroshnichenko is a Doctor of Physico-mathematical Sciences. In 1983 he graduated from the Faculty of Mechanics and Mathematics of Leningrad State University (astronomy), in 1992 he defended his PhD at the Pulkovo Academy of Sciences, in 2008 – his doctoral degree at the SPAO RAS. He worked at the Pulkovo Observatory, as a postdoc at the University of Toledo, at the Max‑Planck‑Institut (Bonn) and as a professor at the University of North Carolina at Greensboro. Co-author of international projects and conferences on the B[e] phenomenon. He identified a new FS CMa class, discovered >50 members/candidates, established the duality of a number of B‑stars and the parameters of Luminous Blue Variables.

The scientist made a significant contribution to the promotion of KazNU's international image. With the support of the professor, KazNU held an international scientific conference on hot stars in 2024. Since 2014, 9 PhD theses have been successfully defended at KazNU under his leadership.

The professor told the audience about the stars in an entertaining way, focusing in detail on their definition, classification and evolution. Anatoly Sergeyevich presented a brief history of the development of ideas about stellar evolution, as well as examples of observed phenomena in the process of research.

The scientist noted that the evolution of stars is determined by the processes of energy release occurring in their bowels. These processes have been well studied in the last half century, so that the theory of evolution reliably describes the properties of isolated stars at all stages of their evolution. However, with the development of high spatial resolution methods and regular sky surveys, it turns out that a significant part of the stellar population of our Galaxy is represented by gravitationally coupled systems consisting of two or more stars. "The interaction of the components of such systems, expressed in the exchange of matter and the formation of circumstellar shells, leads to the emergence of phenomena, the observation of which allows us to better understand the processes at different levels of the structure of the Universe",- the lecturer emphasized.

After the lecture, a discussion took place, in which students, undergraduates and doctoral students of the faculty actively participated, asking Professor A.Miroshnichenko questions of interest. The scientist tried to answer them fully and in detail.
