RaiKatku.com – It is very difficult to collect detailed information about exposes. The parent controls the light of the stars from the extrasolar planet, which makes it difficult to see the telescope.
But now a team that uses the latest technology at the Cake Observatory, has taken a big leap in the observations of expositions and discovered water in the atmosphere of the planet, which is 179 light-years away.
In the heart there is a star named HR8799 in the Solar System, and planets: HR8799b, C, D, and E. This system is 179 light years away in Pegasus Star, quotes from Cosmos Today, Sunday (11/25/2018).
Star himself is the main sequence of 30 million years. This is famous for many reasons, including his fantastic stars.
But it is important for other important reasons.
In 2008, scientists announced that they had seen three exponents around the stars directly using cakes and a miniature telescope like stars and stars – HR 8799, B, C, and D. Then in 2010, they announced the fourth planet, HR 8799 E Search.
This new announcement is made on previous work since 2008, and astronomers behind this research have written a new ad & # 39; well-paced & # 39; Make a call and build a better way to get the images out.
The new observation is HR 8799 C, which was first found in 2008. This is a huge gas giant, which is seven times more than the guru's circulation of its stars every 200 years.
This new direct observation confirms the presence of water in the atmosphere and supports methane deficiency.
This new inspection cake comes with a strong combination of two telescoping techniques. The first is adaptive optics.
Adaptive optics prohibits the opaque effects of Earth's atmosphere. The second cake is 2 telescopes, which is a high spectrometer called the nearby Infrared Cryogenic Eicher Spectrograph (NIRSPEC), a high-resolution spectrometer that works in infrared light.
Kaltech and research scientist astronomer Professor Dmitry Mate said, "This is the technology that we want to use in life to see signs of life on the planet Earth. We are still not there, but we are moving forward." The JPL operated by NASA for captive and co-authors of the study presented these findings.
New findings are released in Astronomical Journal. Chief writer G. Wang, a former postdoctoral scholar in Kleach and now an assistant professor at Ohio State University.
So far, astronomers have created a direct image of more than a dozen extrasolar planets. The HR 8799 system is the first multi-planet system that has been done directly on the image. But the picture is the first step in this study.
Once taken, images can be analyzed for chemical composition in the atmosphere. This is where the spectroscopy comes. In this case, the good capabilities of NIRSPEC are key.
NIRSPEC is a tool on cake 2 telescopes that work in L-band infrared. The L-band is a type of infrared light with a wavelength of about 3.5 micrometres, and has spectrum in many detail with chemical fingerprints.
"L-bands have forgotten because the sky is bright on this wavelength," Mawt said. "If you're an alien looking at an L-band, you will see a very bright sky. It's difficult to see the exposed by the screen."
By combining L-band spectrophotometry with adaptive optics, they conquered the difficulties of viewing the planets, whose light was almost submerged by their stars. They are able to measure the most suitable on the planet, confirm the presence of water and absence of methane.
"Now, with cakes, we can already know about the physics and dynamics of these fantastic giant planets, which are not like our own solar system," Wang said.
"Now we are more confident about methane deficiency on the planet."
"This is probably due to the combination of the atmosphere of the planet. Methane, which we hope is on the surface, can be reduced if the sensation process contains deep levels of the planet which is not methane," Wang added.
The Mawt team has prepared the next and most recent equipment at the cemetery. This is called KPIC, (Cake Planet Image and Characterizer).
KPIC will use adaptive optics and spectroscopy, but for better effects. With KPIC, astronomers can describe their planetary asteroid from planetary planets and HR 8799C.
And the future for imaging extrasolar planets is more brilliant. The technology behind adaptive and spectroscopic optics that will help in the image of the planet, will be used in our future telescopes.
"KPIC is a spring board for our future thirty-meter telescope equipment," Mevet said.
"For now, we will learn a lot about the different ways in which we have created planets in our universe."
