Biography:
He was born March 15, 1952 in the Kostylivka village of Transcarpathian region of Ukrainian SSR. His father, Ivan Romanyuk, worked as a log truck driver in Forestry Plant of urban village Great Bychkov , and his mother, Maria, was a trafficker. For some reason, he loved to watch the starry sky, and as he went to the local eighth, he had already dreamed of finding a "moonstone".
When studying at an 8-year-old school in his native village, which he graduated in 1967, he showed the ability to exact sciences, especially in physics and mathematics, in addition to the aforementioned subjects, he was especially fascinated by astronomy. Then he continued his studies in the neighboring Dilove village.
During 1970-1974 he studied at the Faculty of Physics of Uzhgorod State University. After completing my studies I received a diploma in specialty "physicist", specialization "teacher of physics". In essence, he studied at the Department of Optics, with the specialization - Astronomy, but for some reason this was not noted at the graduation papers of the University.
After a successful graduation, he has worked as a physics teacher at Kosivsk Polyana Secondary School for one year. And then with his former fellow student Yu. Yu. Balegh go to the Kuban to the Zelenchuk village of Karachay-Cherkessia Autonomous Republics where they arranged to work a special astronomical observatory of the Russian Academy of Sciences, settled down in the Bukovyna scientific town. At the observatory, he began to work in scientific work, he went from senior laboratory assistant (1975—1979) to a leading researcher (2005-2011), working as a research associate during 1986-1989 and as a senior research associate in 1989-2005. Since 2008, he has been the head of the group of studies of stellar magnetism of the Special Astrophysical Observatory of RAS in the Nizhniy Arkhiz city and in 2011 he chooling the laboratory of dawn magnetism.
In 1982 he graduated from the postgraduate studies at Special Astrophysical Observatory of the Academy of Sciences of the USSR.
In 1986 at the M.V. Lomonosov Moscow State University he defended his Ph.D. thesis: "Investigation of the manifestations of the fine structure of the magnetic field in the spectra of chemically peculiar stars".
in 1995 he opened a young star (about 1 million years old for the non-cretionary theory of origin of the Universe) in the constellation of Orion, that he committed by using the largest telescope in World at that time.
In 1998, he became a member of the International Astronomical Union.
In 2004, he defended his doctoral thesis at the Special Astrophysical Observatory of the RAS: "Magnetic fields of chemically peculiar stars of the main sequence" on the specialty "01.03.02 - Astrophysics and Radio Astronomy".
Since 2006, he has been the deputy editor-in-chief of the Astrophysical Bulletin magazine.
As a doctor of physical and mathematical sciences, the professor gives lectures on astrophysics to students who come from the university in Rostov-on-Don and other universities.
He wrote about 200 scientific papers published in international and Russian astronomical journals.
In 1993-2015 he was Secretary of the Committee on Large Telescopes of the Russian Academy of Sciences
In 2016 he was awarded the title "Honored Worker of Science in the Karachay-Cherkess Republic of the Russian Federation".
Freely owns, in addition to his native Ukrainian, Russian, English, Hungarian languages, participates in international scientific conferences in the US, India, Canada, Germany, France, Greece and some other countries on the problems of the sky, gives interviews at press conferences with these issues.
The main scientific works of J.I. Romanyuk belong to the field of stellar magnetism research. Author of more than 180 publications.
In the mid-1980s, J.I. Romanyuk proposed and led a large-scale project to search for magnetic chemically peculiar stars at the 6-meter Large Azimuth Telescope of the Special Astrophysical Observatory. Anomalies in the energy distribution in the continuous spectrum of these objects were used as a criterion for selecting candidates for observations. The criterion turned out to be effective, about 75% of the stars selected for observations with the Large Azimuthal Telescope turned out to be magnetic. By the end of 2015, about 180 new magnetic stars were found, which is more than 1/3 of all known objects of this type.
Since the late 1990s, J.I. Romanyuk and his colleagues are studying very slowly rotating magnetic stars. He managed to increase the number of such objects from 5 (in 1995) to 18. Among the discovered objects, in particular, 2 new objects with a rotation period of more than 20 years. A very long period (more than 5 years) was confirmed for another 12 objects of this type. J.I. Romanyuk showed that fields of complex topology are observed only in relatively young stars, whose age does not exceed 20 million years. Old stars exhibit a simple dipole field configuration. These data serve as strong evidence confirming the theory of the relic origin of the magnetic fields of these objects.
He is the initiator and organizer of nine international astronomical conferences on the topic "Magnetic Stars", was the executive editor of the proceedings of these conferences.
J. I. Romanyuk and D. O. Kudryavtsev compiled a new catalog of magnetic SR stars by 2008, containing 326 objects with reliably detected magnetic fields and 29 with a high degree of probability of having a magnetic field.
D. O. Kudryavtsev, J. I. Romanyuk and E. A. Semenko and other employees of the Special Astrophysical Observatory of the Russian Academy of Sciences in the spectrum of the star HD 178892, the magnetic field of which was first discovered as a result of observations with the Zeeman analyzer on the BTA Main Stellar Spectrograph, was detected split polarized Zeeman components of some lines. In the course of the study, the effective temperature of the star was determined (Teff = 7700 ± 500 K) and a preliminary analysis of the chemical composition was carried out, which, as it turned out, is characteristic of roAp stars. In terms of surface field, the star HD 178892 was the record holder among cold CP stars.
D. O. Kudryavtsev, J. I. Romanyuk, and E. A. Semenko together with G. A. Solovyov in 2006 based on spectra obtained at the OZSP of the BTA telescope with a resolution R of about 15000 and a signal-to-noise ratio of 100-200, determined the radial velocities and rotation velocities of 32 new magnetic SR stars.
J. I. Romaniuk and E. A. Semenko studied the spatial distribution of magnetic SR stars in our Galaxy, their kinematics and some physical parameters depending on the position in the Local System.
I. A. Yakunin, G. A. Chuntonov, E. A. Semenko, and E. I. Romaniuk observed linear polarization in the spectral lines of the unique star HD 37776 with an anomalous excess of helium.
In 2015, J I. Romanyuk, D. O. Kudryavtsev, E. A. Semenko, and I. A. Yakunin summed up 15 years of work on monitoring the magnetic field of the star HD 965.
