For the first time, American astronomers from the University of John Hopkins and other science centers confirmed the presence of crystalline water ice on a dusty disc around the HD 181327 star in 155 light years from the ground. The opening was made using James Webb Space Telescope. The study was published scientifically magazine Nature.
The team found that the ice was distributed unequally by the system – the concentration reached 20% in the external areas of the disc, where the temperature was lower and practically closer to the star.
“We found not only water ice, but also in the Saturn rings and similar to the objects of the Kuiper generation,” he said.
The young star HD 181327 (23 million years) is surrounded by an active debris disc, where the conflicts of the ice bodies are continuously. These operations release the microscopic particles of “dirty snow” recorded by Webbu.
According to Co -Straghor, Christine Chen has been waiting for such data for 25 years. The discovery confirms that water plays a key role in the formation of planets – affecting the formation of gas giants and can be delivered to the stony -tailed stars and asteroids.
In the HD 181327 system, ice detection opens new opportunities to examine similar processes in the early solar system. Astronomers are planning to continue to look for water ice in other star systems to better understand the mechanisms of the planets and the possible origin of life.
