Astronomers monitoring a star in the constellation Ursa Major bears the symbol WX UMa increased to shine a sudden and very fast so that increased by 15 times in just 160 seconds, less than 3 minutes, which to the surprise of astrophysicists.
Monitoring of the star have been through physicists astronomers at the Spanish University of Santiago de Compostela and astronomers from the Byurakan Observatory Armenian who said that this star is from Earth, 15.6 light-years away, a binary star and the companion star brightest from around 100 times, and this discovery published in the magazine Astrophysics in its issue recently.
Physicist astronomer Professor "Vakhtang Tamazian" Vakhtang Tamazian head the scientific team discovered this change in gloss said the glitter star has increased dramatically in less than 3 minutes, which is surprising really, this also means that the surface temperature of the star changed than 2,800 degrees Kelvin to more so seven times almost over this time period is very short, note that the average surface temperature of this type of stars ranging from 2000 to 3700 degrees Kelvin, and spoke physical processes too many during a very short time also standing, their brightness and then return to normal after 10 minutes.
Explains Professor "Tamazian" They do not know what exactly happens in the soles of the star in order to make it shine dramatically during this period is very short, showing the center of a small instability in the plasma star, standing, the magnetic field for an average of normal, and then turn the energy field Magnetic to kinetic energy, and turn the kinetic energy coming from the plasma of the star to heat energy in the layers of the star of Foreign Affairs, and the temperature change in the star can astrophysicists to measure changes in the spectrum of radiation of the star, the information of interest to astrophysicists because it helps them to study the evolution stellar better .
