of the Hubble Space Telescope He saw a young protoplanet like Jupiter supporting a common object world establishment theory, according to recent research.
The subject of the Earth image AB Aurigae b, a young gas giant is about 531 light -years from our day which is estimated to be about 2 million years old. Gas and stellar scientists have discovered what is collected around the star in what is called a circumstellar disk.
But AB Aurigae b seems to be supporting long -held theories about the mechanics of the formation of the earth in terms of its size and location. In fact, according to the researchers who found this exoplanet, it is known to support a concept of earth formation called “Disk not stable“- which is described as” strong and violent. “

Because jovian hotelsThe concept of accretion is “a path down to the top through which the stars embedded in the disk grow from small objects – with large amounts from dust to to the rocks – pounding together as they orbit a star. then the gas slowly collects from the disk, “according to a word describing this new study.
AB Aurigae b, however, orbits its star at a distance of 8.6 billion miles, which is more than twice the distance. Pluto from our day. Because of that distance, scientists believe that a planet like AB Aurigae b. But the protoplanet is much larger than Jupiter, and in its infancy. Scientists believe that this can only be done through a different approach called “disk instability”.
This method is a “top-down model in which a large disk cools around a star, allowing gravity to quickly separate the disk into one or more large Earth-particles,” according to the same statement. .
To determine if this exoplanet was formed from this alternative activity, the researchers compared data from the Hubble image of AB Aurigae b with data from the global imagery maker SCExAO in Japan. Subaru Telescope in Hawaii.
“The value of data from space and telescopes around the Earth is significant, because it is very difficult to distinguish between child stars and complex features that are not related to the planets,” he said. says the word.
Of course, not only were Hubble’s new images used in the study – research director Thayne Currie of the Subaru Telescope and Eureka Scientific found that Hubble’s archive data was important to intelligence. “We can’t see this application on the order of one or two years,” he said. “Hubble has provided a time limit, combined with Subaru data, of 13 years, that is enough to detect orbital motion.”
With a lot of data from both manufacturers, scientists have been able to validate their basic accretion theory, while more information will be made using the The James Webb Space Telescope after coming online later this year.
