In a recent development, scientists able to find out a belt-like structure around a distant star, located around 320 light-years away from our solar system. The development is significant, as this is the first time when scientists able to detect a Kuiper-belt feature in another solar system.
The star named HD 141569A is having an inner ring structure outside of its solar system. The development will help scientists to unveil new details about planetary development. HD 141569A is only five million years old, having three times of mass than that of the sun in our solar system.
More about the Development
In 1999, scientists discovered a disc-like structure around the star. In the disc, there are two rings separated by a massive distance of 140 astronomical units. Researchers observe many remnants surrounding the disc. These leftover materials came close, owing to the effects of gravity, and formed a planet.
In our solar system, the sun used to have a disc-like structure formed around 4.6 billion years ago. Today, this structure renamed as Kuiper belt. After the process, the leftover material called debris disc. The debris disc generally extends for a large distance, often measured by AU.
Researchers analyzed the twisted electromagnetic radiation came from that region near the star HD 141569A. Therefore, scientists able to draw a ring-like structure around HD 141569A star, which peaked after 44 AU from the star. Scientists could not be able to detect any planet formation around the star. Still, the presence of another ring-like structure, placed nearby to the star, confirms the future development of a planet. With extensive research, researchers found that the mass of the upcoming planet is equivalent to the mass of the largest planet in our solar system- Jupiter. Some scientists also predict that the mass of the planet might slightly lower than the mass of Jupiter.
The development will help scientists to analyze the formation of a planet and the belt structure around a star.
