Astronomers from Moscow state University named after Mikhail Lomonosov discovered that the star TYC 2505-672-1 has a record period variability Shine. Dutch scientist Rolf Jansen from the University of Arizona confirmed the data of the Russian colleagues. The period of variability lasts 25245 days.
Astronomers from Moscow state University named after Mikhail Lomonosov discovered that the star TYC 2505-672-1 has a record period variations of light (eclipses). Devoted to the study of the Preprint, the authors published on the website arXiv.org, as briefly reported in the press release of the Moscow state University received by the editors "ru".
Recent observations of TYC 2505-672-1 allowed scientists to show that the brightness of the star decreased almost in one hundred times. Shone was previously considered extinct. The scientists ' conclusions were confirmed by observations of a network of robotic telescopes MASTER, 6-meter BTA telescope, and archival materials the library of Harvard Observatory.
Dutch astronomer Rolf Jansen from the University of Arizona confirmed the data of the Russian colleagues: the fall of the Shine of the star TYC 2505-672-1 happened in 1942-1945 years. The star, according to the calculations of the scientist, has a record period variability, is $ 25245 days (approximately 69 years).
Scientists believe that the star TYC 2505-672-1 in the Small constellation of Leo is a binary system, but the nature of its companion is still unknown. Previously, the record period of the variability of the brilliance belonged to a star called Epsilon of a Charioteer. It eclipses recur through 9890 days (over 27 years).
