Astronomers captured an image of a potential planet around the star
Astronomers believe that they have caught a planet in the work of formation, something that has never been seen before.
After a star is ignited, the planets come out of the remaining gas and dust, and it is believed that the formation planets or planets form a disc for the host star. While astronomers have seen this protoplanetary disk around many stars, they have taken an action anytime before being photographed for the construction of a real planet ever before.
While the earlier comments of this star did not reveal anything that could revolve around it, the team made by the discovery used a separate equipment that saw it in a different wavelength.
The author of the study, published in the journal on Monday The astrophizical journal lettersIt is said that he has not yet confirmed that what he has captured is the formation of a planet or protoplanet.
“We have only one image (in) only one wavelength,” Francesco Mayo said, a doctoral researcher at Florence and the lead author of the study. “We have three images where we don’t see this object. So we need to understand the qualities of these candidates protoplanet.”
The object is about 440 light years away in a binary, or double, star system, and is believed to have twice the size of Jupiter. It revolves around its host star at a distance from the Sun of Neptune.
‘Like a cappukino’
Maio described the discovery of the potential planet in the disc in a unique way.
“The disk is like a Cappukino. The planet is like a spoon in Cappukino. And when you move the spoon inside the Cappukino, you start making a spiral,” he said.
Although scientists have previously observed the spirals, Mao says this is the first time they are able to see what is potentially the reason for them.
“We are not yet able to see the planet that bothers and produces a spiral,” he said. “So you already see this Cappukino with the spiral, but we never see a spoon.”
The discovery was made using a very large telescope (VLT) and its extended resolution imagers and spectrographs at the European Southern Observatory (ESO) in Chile.
The disc was imaged by another team of astronomers using a separate device (spectro-polyimetric high-contrasting exoplanet research), which can block a star light to see if there is any object around it. But previous researchers found nothing to revolve around the star.
Nevertheless, researchers say it is promising.
“This is an interesting observation. People have long been looking at these spiral structures in the protoplanetary disc,” said Hano Rain, an associate professor at the University of Toronto and an exoplanet researcher who was not part of the study.
“The object that is usually missing is actually making those spiral weapons, or which is being made in those disks. And here this team has found a strong candidate of an object that is based on one of the spiral weapons that can be a planet.”
2 stars, different environment
Another interesting turn for this discovery is that there is another star in the system, whose atmosphere is very different.
The pair is collectively known as HD 135344AB. This potential planet that is revolving around is HD 135344B.
Both the stars are almost the same age, Mao said. Nevertheless, there is no protoplanetary disc in other Star – HD 135344A in the system.
“It’s very interesting, speaking scientifically, because we don’t know why two very stars developed together as two different systems,” Mao said.
Earlier this month, astronomers saw another star with VLT and Sphere Instrument of ESO and Found a planet About 10 times with mass of Jupiter.
Although this is a mystery, it is a question that Monday’s study will require further investigation, whether a protoplanet in the gas and dust disc, Maio said, and possibly will require to use other wavelength to look.
