Star several times the mass of the sun depends on the object "placenta" growth.

<P> New study found that several times larger than the Sun, massive stars, "was born," the former relies on a similar structure of the human placenta lessons from space to grow "nutrients" - substances such as dust and gas. .</ P> <P> 1 issue of The British "Nature" magazine published the Purple Mountain Observatory Jiangzhi Bo, Yang Ji, Japan's National Astronomical Observatory of Taharu per show, Shen Chuan United States, the British astronomer Hough and other research results, that is .growing around massive stars, "Arch chart" - a containing magnetic field, dust and gases. .</ P> <P> they got a star in Orion's high-resolution near-infrared polarization images, which proves the star around, "Arch chart." .This is the first time in human history of massive star formation law of evidence. .The discovery of human understanding "fetus" to provide a reference of the solar system. .</ P> <P> star is from Earth objects nearest massive star, is the most popular stars of the astronomical community. .</ P> <P> 41-year-old Jiang Zhibo researcher, massive star formation law of the international astronomical community has been a hot topic, the so-called high-mass stars is more than 8 times the solar mass stars. .</ P> <P> Currently, the astronomical community for small, medium-mass star formation law has reached a consensus: the initial gravitational collapse through the post with the quality and the formation of accretion. .But the massive star formation law is unclear. .In this regard, there are two major speculation the astronomical community: a massive star that is through an accumulation of low-mass stars formed; the other is equivalent to a small star formation, that is through gravitational collapse and the initial post with the .the quality of the formation of accretion. .The latter theory must be "arch chart" the existence of; and merging theory is that there is no such system. .Therefore, by astronomical observations to confirm the disk around the massive star system as the correct identification of these two theories or not the key factor. .Prior to these two theories lack observational evidence, because massive stars are very rare, and usually far from the solar system. .</ P> <P> "BN protostellar objects" by British scientists in 1967 found that the quality has been considered one of the original stars of the original sample. .This is an emerging star in the age of about 10 long live, the quality of at least 7 solar masses, but it is generally believed that the quality of solar masses in between 8-13. .</ P> <P> "This discovery is of great significance. We know that the formation of the solar system 4.5 billion years has been the history of the condition for the formation of the solar system first, we can only guess, but 'not yet born' of this .growth pattern of the day, compared with the human body to understand the fetal period provides an important reference for the solar system. "Jiangzhi Bo said. .</ P> <P> he said, "BN protostellar objects" is just the space of massive stars in the "little man", for larger mass stars, needs more evidence to explain the formation of observing the law, this .found just the beginning. .(End) </ P> <P> </ P> </ p>.
