At the top end, the icewater particles were found in frozen kuiper belt in another star. The discovery, made by Telescope on James Webb, a major step in applying the filling gaps in our understanding of how the exoplanets are developing.
As with Kuiper belt to us SOLL SystemThis extraterrestrial debris disk is likely to be filled Comets,, Dwarf planets And a lot of ice particles with the ice with the greater bodies as a result of collisions. The debris disk, as well as our Kuiper belt, consist of remnants of a larger disk that once surrounded the star – called HD 181327 – and maybe bare the planets. Instead, to brighten, no regional planets found so far.
Because water is a common molecule in the universe, its presence in HD 181327 debris disk is not surprised. In fact, Excocomets found around other stars; In our solar system, comets from fierce, frozen Kuiper belt and the oort cloud, so excokomets should come from an area of the same.
However, while garbage around other stars are known and imagined since the infrared astromy satellite (IRASS) found in the water, we found no ice water so far.
Using the James Webb Space Telescope . Located 155.6 Light-year away, they are about 18.5 million years of age. This is the most young compared to our DAYAge of 4.6 billion years. The star is a f-type, means it’s a little hottest and slightly bigger than our day.
The NIRSPEC sees the SPECTRUM SPECTRUM signature of a wavelength of 3 microns (million a peak to come to 3.1 microns. This spikes of the spectrum, “caused by the light of the ice-ice millimeters of millimeters of millimeters in the size of ice. It is similar to the size of the particles of Saturn’s rings, for example, and ice is likely to be frozen around the Motes of the Interplanetary Aw.
“Mainly, we saw a water reservoir in the water,” Xie told Space.com.
This ice-water reservoir can help develop any planet system that may exist around HD 181327. Gas Giant Example the planets Ice-Ice helps the material stick with a giant type of mush that can be the basis of a large, rocky core to hang on gas to form a giant planet.
The water of terrestrial planets such as WORLD as well as given to asteroids and / or comet formed beyond the snowline and wealthy ice-ice. Therefore, the detection of ice ice in HD 181327 debris disks means that materials are there to help develop any planets in starsEven at this time there are no planets found in the system.
“The presence of a water reservoir in the planet planets around HD 181327 gives the potential to deliver the water to adjacent planets,” Xie said. “But we don’t know what can be delivered by street water to the planets of the system.”
Temptation to make comparison between our Kuiper Belt and HD 181327 Debris Disk. However, Xie warned that it was literal in comparison, because there were important gaps in our knowledge of frosting belts and how it was related to each other. However we can do some general conclusions.
“The presence of ice-ice on a disk disk around a young star suggests that frosting belts can form easily in cold solar regions,” he said. Their early availability may have helped the development of planets in the solar system.
However, the disk shaped by the planet around the HD 181327 has been done now, and any planets are currently formed. In addition, JWST observations showed how disks inside the debris disk lost the light of the star ultraviolet. Tinderal line stability for water-ice on the inside of the debris, 80 to 90 Astronomical units . Forward, between 90 and 105 astronomical units, the masses of the ice water increase in 7.5%, and between 105 and 120 astronomical units. Indeed, Fresnel Peak has been found between 90 and 105 astronomical units.
So, what happened? Ultraviolet light from the star can vaporize ice-ice, but something seems to change it – otherwise, the ice water on the discount disappears at the moment.
This addition is likely to come from collisions between dwarf planets, cometary nuclei, micrometeoroids and other flotsams and flotsams and jetsam surrounding the Darks Disk. Each effect lays out more dust and ice grains in space, and every big impact sheds rainfalls away. If there is enough dust today, it can also protect ice ice from ultraviolet light. The dust has already been found to include grains of olivine and iron sulfide.
Meanwhile, atacama is large milimeter / submillimeter row (Alma), which is a chile radio telescope, found carbon monoxide on a discish disk, which can also be released in space in collisions with murderous bodies. Besides, the NIRSPECC in JWSTSEC found the tentative evidence for the presence of carbon dioxide in the disk region between 105 and 120 astronomical units from the star, even if it should still be confirmed. A second specteral line for ice-ice, at 4.5 microns, also seen in the 105 astrano regions that can be rich in volatiles: gas with short spray points.
Now that JWST shows it can find water systems in the exoplanetary systems, we can expect more widespread discoveries in the future. In fact, Xie and his team have already worked it.
“Except for HD 181327, we also saw other JWST and Nirspec systems,” he said. “We are currently working on printing data, so stay fast!”
Discovering ice ice around HD 181327 was published on May 14th Journal NATURE.
