ScienceLovers ~ A new study has revealed that some of the biggest and brightest stars in the universe is packed in a single cluster.
Researchers using the Hubble Space Telescope to image a young star cluster R136 in ultraviolet light (UV) for the first time. The cluster is located in the Tarantula Nebula in the Large Magellanic Cloud, about 170,000 light-years from Earth.
Scientists are hunting a huge star and very hot, which memancarkansebagian of their energy in the UV spectral range. And the researchers got the jackpot, dozens of stars in R136 at least 50 times larger than the sun, and nine star has a mass of more than 100 solar masses. (One of these gigantic, previously found is R136a1, the star of the greatest mass that is known in the universe, more than 250 solar masses, NASA officials said.)
This giant is very luminous and very large; together, nine of the largest has a brightness of about 30 million times brighter than the sun, the researchers said.
The number of giant R136 (which runs only a few light-years), should membantuastronom better understand how massive stars are formed, said study team member.
"From what we know about the frequency of massive merger, this scenario can not explain all the stars are really great at R136, so it would appear that the star can be derived from the star formation process," Caballero-Nieves added.
"There is a suggestion that this monster star resulting from the merger is less extreme in close binary systems," said co-author Saida Caballero-Nieves, from the University of Sheffield in England, said in a statement.
The researchers also established that massive stars rapidly lose mass as well as having a life of simgkat (which often ends in collapse into a black hole). These stars eject material to the mass of the Earth every month, at speeds that can reach 1 percent the speed of light.
The study is published in the Monthly Notices of the Royal Astronomical Society.
