Astronomers using space observatory ESA Herschel for the study of the turbulent early stages of the evolution of a star similar to the sun, have found evidence of strong stellar winds that can help solve the "meteorite" the mystery of our solar system.
Absolutely "quiet" on the face of the stars of the night sky is actually represented by high "ovens", which are driven by the rapid processes - and our sun, whose age is 4.5 billion years old, is no exception. To look at the early years of the stars, astronomers gather clues not only in the solar system, but also far beyond its borders, focusing on the young stars in our Milky Way galaxy.
According macromolecules CeciliaCeccarelliiz InstitutedePlanétologieetd'AstrophysiquedeGrenoblevo France, who conducted the study along with SarstenDominikiz UniversityofAmsterdamv macromolecules Netherlands, she and her colleagues found that the proportions of the two chemicals - laid the foundation of the first carbon and oxygen, and the basis for the second - nitrogen - much less in this object, than any other known protostar.
In extremely cold environments violation of the proportions of these chemicals could arise, but none with a relatively "high" temperatures of minus 200 C, recorded in star formation OMC2 FIR4.
The most common molecule in the clouds of star formation macromolecules - hydrogen - can be destroyed due to the impact of cosmic rays, energetic particles that permeate the entire galaxy. When hydrogen ions are combined other elements: carbon, oxygen macromolecules or nitrogen.
Nitrogen compounds are also typically fast enough to disintegrate, releasing even more hydrogen to form compounds with carbon and oxygen. It should be noted that the most common macromolecules in the "stellar nurseries" are precisely oxygen compounds.
Astronomers believe that a strong wind of high-energy particles, was characteristic of the early solar system. This finding helps to explain the origin of a particular chemical element found in many meteorites.
Meteorites - the remains of interplanetary debris that survived the "journey" through our solar system. According to Dominik, some elements found in meteorites indicate that these rocks in the distant past contained beryllium isotopes - this is very unusual, as it is unclear how he could get there.
Formation isotope Beryllium-10 in the universe - it is one of the main secrets of not only the solar system, but the entire universe, which is called "meteor mystery." The fact that this isotope of beryllium is not made any "interior" of stars or during supernova explosions.
Beryllium -10 can be formed only in collisions macromolecules of very energetic particles with heavier elements such as oxygen. However, macromolecules due to the fact that the isotope decays macromolecules fast enough, it must be formed shortly before penetration into the rock, which then turns on the Earth as a meteorite.
