Scientists have discovered another star, the luminosity which decreases periodically, like “alien star” KIC 8462852.
Star RIK-210 is in the so-called OB Association, Scorpius — Centaurus — 472 light-years from the Sun.
The failures in her glitter dostigao 15%, but, unlike star Tabby, eclipses occur with periodicity 5.67 a day and synchronized with the rotation period of the star itself.
With the help of spectrometric observations, the scientists ruled out the possibility that eclipses are caused by a second, less bright star or brown dwarf. In addition, eclipses can be caused by a single spherical body, because each time have a different shape and duration. According to scientists, the cause of eclipses can become a cloud of abnormally cold plasma inside the magnetosphere, rotating synchronously with the star.
Formerly Professor of the Catholic University of Louvain in Belgium Leen Decin told that the Sun would destroy all life on Earth in five billion years when it becomes a red giant.
