The Hubble space telescope to watch the ship base Italo star
According to the United States space network today reported that the first European astronomers have detected a double star system 2 huge stellar wind has a strong impact, and produces a high-energy x-ray.
Astronomers: suspect Galaxy Evolution history
Astronomers discover exotic neutron star
In the star stars
This violent marine base Tuita (Eta Carinae) double star system of the quality of the solar quality 100-150 times the luminance than the Sun high 4 million times. This so-called Super Star series contains 2 big stars, his second star discovered until 2005. Astronomers have always suspected this double stars will release the high-energy x-rays, but they have no instruments to detect this Ray. Recently, the European Space Agency's "Integral" telescope finally detected by base Italo star launches this high-energy x-ray. World Science report
Get this discovery of Belgium Liège University's Jean-Reyes holds non-· preden said: "this x-ray intensity than we expect small point, but this is decisive for the first time, this is very good. "Furthermore, this intense x-ray is thus enormous stars wind impact. These particles emitted by the light and other radiation is so powerful that ship base Italo star stellar wind speeds can reach 1500-2000 kilometers per second. Because this 2 star is so close to, its stellar wind of violent collisions can make the temperature reaches tens of millions of degrees.
"Integral" telescopes see boat base Italo star surrounding high energy x-ray
The electrons are stellar wind shock wave magnets capture, jumping, gathering have enormous energy. When they finally broke out shock waves, to a low frequency of a photon, so that the collision between a photon to release energy, produces the "Integral" telescopes observed by high energy x-ray. Scientists hope to discover other stellar wind impact of satellite positioning system, but because of the massive stars rarely, and great binary system consisting of stars is less, it is difficult to find. Leyden represents our Galaxy may only 30-50 this binary system can show clear signs of stellar wind impact. Astronomers last year in our own Milky way, next to the small Magellan Nebula in another binary systems HD 5980 Department detected HD 5980 emits x-rays, just not strong. But from the boat base Italo satellite detection of x-ray is a high energy. Astronomers estimate shipping base Italo star due to Jet and had lost a day Earth quality material, is about 5980 lost material HD ratio of 140 times. World Science report
Understanding of stellar wind of this kind of x-ray emission is important, because the effect of stellar wind star's development and chemical evolution of the universe, in addition also serves as the energy of the galaxies.
