Fengyun homeless star now in the 30 Doradus nebula edges. The 30 Doradus Nebula is located near the Large Magellanic nasa esa Cloud, a bustling star "breeding ground." The findings suggest that the local universe (our universe where) the vast majority of high-mass stars are located in the 30 Doradus nebula, a massive star to become a research lab unique. 3 Doradus nebula is also known as "Tarantula nasa esa Nebula", about 17 million light years from Earth. R136 is located nasa esa in the center of the nebula, stellar quality nasa esa of some interior can reach 100 times the sun.
"Hubble" telescope observations will help astronomers learn more about the discovery of a massive cluster of activity nasa esa patterns. COS project team members responsible for the Fengyun runaway star observations, the U.S. Space Telescope Science Institute in Baltimore, Nolan Val Byrne said: "These observations have important significance, because like this occurs in a high intensity Since a large cluster dynamic processes within nasa esa a period nasa esa of time can be predicted theoretically, this could be directly observed in this region for the first time this process the first time found a relatively nasa esa small mass of runaway star fled more smaller Orion Nebula Cluster thing is already half a century ago. predicted recently proposed believe nasa esa the vast majority of massive young star clusters nasa esa also exist of this phenomenon, this observation can be confirmed this prediction, which is the first in the history of time. "
COS project team members, the Space Telescope Science Institute Danny Lennon said: "Astronomers generally believe, R136 is a very young star clusters, most massive nasa esa stars in the cluster is still not in the form of a supernova explosion. This means that the Fengyun runaway star cluster must be expelled through nasa esa the dynamics of interaction. "This observation of runaway star research team led by the Royal Observatory Edinburgh, Chris Evans, research The findings appear in the May 10, 2010 online edition of "Astrophysical Journal Letters" on.
When will this star as the target calibration COS, "Hubble" Project astronomers unexpectedly found another clue. COS was in May 2009 in the implementation of the fourth "Hubble" maintenance tasks installed. These UV spectral observations nasa esa in July 2009 showed that this "wayward" star has been charged particles released so far known in the most violent stellar wind, described the star quality of a huge, probably 90 times the sun. In addition, the star must be very young, only about 100 to 200 Viva Viva, because massive stars can only "survive" a few hundred million years.
