Scientists can not explain the behavior of the mysterious star
A group of scientists using the European X-ray telescope XMM-Newton has discovered a previously unknown star with impressive size, but like the star leading dwarf. New Star Xi1 Canis Majoris in size to 15 times as massive as the Sun, but every five hours she shoots beams of x-ray particles, which is quite unusual for this type of objects. According to scientists, this behavior would normally for the "degenerated stars" - White dwarfs, neutron stars, or magnetars, while Xi1 Canis Majoris is a traditional star.
According to scientists, the surface temperature of the star is about 28 000 degrees, this temperature is not sufficient to start the reaction with the plasma for the production of X-rays. European scientists say they do not yet explain this strange behavior star, remote from us at about 1400 light years away in the constellation Canis Major. particular interest of scientists is extremely strong magnetic field of the star - it is almost 10,000 times stronger than Earth's and 5000 times stronger than the magnetic field of the Sun.
The magnetic field of the star into space makes a stellar wind - a stream of particles coming from the star.Since the star is a bright source of X-ray radiation, it is engaged in research observatory XMM-Newton.Scientists believe the reason for such a bright glow is that the shock waves of the magnetic field of the star accelerate particles stellar wind, because despite the fact that the temperature of the star is incredibly high, it is still not enough to emit the amount of X-rays, which scientists have observed.
"This work has shown that the stellar winds and high-energy radiation that emanate from them must be related in some physical mechanism occurring inside a star "said lead researcher Lydia Oskinova University of Potsdam in Germany. In other words, the fact that these photons and X-ray pulses inside the star act in unison to indicate the relationship between them, which may help explain the unique activity of the star.
