From coursework – to the international publication
The authoritative scientific journal Galaxies (indexed in Scopus and Web of Science databases, Q2) published Shahida's article "HR 4049: a Spectroscopic Analysis of a Post-AGB Object". This research work was carried out under the guidance of aldiyar Agishev, scientific director and co-author of the article, associate professor of the Department of Electronics and Astrophysics. The work is devoted to the spectroscopic study of the HR 4049 object at the post – AGB stage-the last stage of the life of medium-mass stars. This stage lasts only a few thousand years. Therefore, observing the star at this very stage is considered a real success for astronomers. During this period, the star distributes active matter and enriches the interstellar medium with heavy elements that form the basis for the formation of new stars and planets. The peculiarity of the HR 4049 object is that it is part of a binary star system. This allows, for example, to determine with high accuracy the parameters of both stars that make up the system. This study opens the way to a new milestone in understanding the interaction of the components of binary systems at the late evolutionary stages.
This story began with a completely ordinary one. In the process of writing the research part of the thesis: "I took new control data on the object of study and proceeded to normal processing of Spectra. However, there were unexpected results: the data showed features that had not been encountered before. I checked my calculations again, no error was found. Based on this, I made a report at a weekly seminar with my scientific supervisors and foreign colleagues. We felt it would be a big discovery when we looked at the results together. At that moment, the idea arose to publish the work in a reputable magazine. This experience taught me not to be afraid of complex searches and not to limit myself to the successes achieved while still in The Bachelor's degree. Based on the results obtained, together with my supervisor and foreign colleagues, we have prepared a new work for Monthly Notices of the Royal Astronomical Society (MNRAS), the leading, first quartile publication in the field of astrophysics. We also developed another article for the regular issue of Galaxies magazine and an article for the University journal Physical Science and Technology. I dream of staying in science. In order to continue working in this direction, I intend to submit documents to the magistracy," Shahida shared her plans.
The study was carried out within the framework of the educational program" Physics and astronomy". Observational data were obtained within the framework of the International Cooperation Program in the field of observational astronomy jointly with the University of North Carolina and the three colleges Observatory (USA), as well as the V. G. Fesenkov Institute of Astrophysics (Almaty). All calculations and digital simulations were carried out in the multiprocessor cluster of the Research Center "Data Science in Astrophysics" at the Faculty of physics and technology of KazNU.
"Even today we are proud that our students are becoming a part of World Science. This publication is an indicator of the sincere interest and persistent work of the student, as well as the high – level educational and developed scientific environment that has developed at the University. Our students not only master the most complex scientific directions, but also make a real contribution to the development of domestic science. This example inspires both our current students and future applicants. After all, science at KazNU begins as a student and gives everyone a real opportunity to become a part of Global Research", - said Nurzada Beisen, dean of the Faculty of physics and technology.
The article was included in the special Circumstellar Matter in Hot Star Systems issue of Galaxies magazine. The full text of the work is available at the link: doi.org/10.3390/galaxies13020026
