The quality of the objects found around the small disk structure or search the target planet 3edyy

The quality of the objects found around the small disk structure: or into the search for planets observed around some massive young stars, gas and dust cloud that can often be observed, but recently scientists around 4 small celestial bodies also detected the mass accretion disk structure art similar diagram: dust gas cloud around a young star. Which is the formation of a planetary body prototype Sina Technology News Beijing on September 29th news, according to the British "Daily Mail" reported that in order to understand the formation mechanism of the planet, one of the best way is to directly observe the procedure. Now, scientists do it. When a star is young, it is surrounded by a disk of gas and dust. It is in such a dusty disk that the planets begin to form. Around some massive young stars, gas and dust cloud that can often be observed, but recently the University of Montreal in Canada and around the American scientists at Carnegie Mellon University in Washington in 4 small celestial bodies also detected the mass accretion disk structure similar to the. The quality of three is very small, basically can be classified into the quality of the ranks of brown dwarfs — most of the three small planets respectively between 13~18 times the mass of Jupiter, and the rest is larger, the quality is roughly about 120 times that of jupiter. The observations will help us understand how stars and planets are formed. At the same time, it also means that the universe may also be hidden in more similar cases of celestial bodies. The scientists observed 4 planets, three star quality is very small, basically can be classified into the quality of the ranks of brown dwarfs — most of the three small planets respectively between 13~18 times the mass of Jupiter, and the rest is larger, the quality is roughly about 120 times of wood star researchers said that the four planets observed in two aged from 42 million to 45 million years. Such age values would make them the oldest known objects to be wrapped by an active accretion disk. Anne Boucher of the University of Montreal (Anne Boucher) is the first author of the paper and the related study, she said: "for us, in the small mass celestial system found in the accretion disk structure is an exciting thing, because those close to the lowest quality small star quality limit objects can still exist around the Accretion Disc the fact that inoculation of the planet, will tell us a lot about the evolution of stars and planets." In such a cloud of dust and gas, tiny dust particles collide with, and gradually become larger, like a snowball gradually "grow up", has been turned into a hill level, then become a mountain, eventually forming the so-called stars (planetesimal) — this is the prototype of the planet. Subsequently, this intense collision and merging process continued until eventually the largest of these survived to form the final planetary body. And in the middle of all the big ones that were eventually retained, some相关的主题文章:
