Researchers have recently found a planet which is shaping around a star 553 light years away. According to the team of U.S Naval Research Laboratory (NRL), a proto-planetary disk (a large disk of material orbiting a newborn star from which a planetary system can form) around a star known as HD 100546 has formed. The team was studying hot gas within the disk by the use of method known as spectro-astrometry, which lets them to spot even little changes.
During the research, the U.S Naval Research Laboratory team noticed a “superfluous” source of gaseous emissions from carbon monoxide molecules that may perhaps not be coming from the disc only. Afterwards, these researchers intended the changes in velocity and place of the extra emission over years of observations and found it was regularly orbiting the star. The proof suggests that they are examining the hot gas that usually surrounds a very young planet.
With the help of continuous modeling, the researchers were able to verify their theory and examine the extra emissions. In fact, the NRL reported that the researchers believe that the gas is coming from a “small circumplanetary disk of hot gas orbiting a forming planet. They also reported that the forming planet could most probably be a gas enormous and about 3 times the mass of Jupiter.
NRL Researchers claim that the matter from large proto-planetary disks feed into circumplanetary disks, which in turn feed into a forming planet. The leftovers of the circumplanetary disk could also add up to the formation of moons.
According to the NRL, this study is actually based on data gathered from 4 observations taken back in 2003, 2006, 2010, and 2013 using the Gemini Observatory and the Very Large Telescope at the European Southern Observatory.
John Carr, a scientist at the U.S. Naval Research Laboratory (NRL) stated that “these results provide a rare opportunity to study planet formation in action. The analysis sturdily suggests we are observing a disk of hot gas that surrounds a forming giant planet in orbit around the star. Even as, such circumplanetary disks have been theorized to surround giant planets at birth and to control the flow of gas onto the growing planet, these findings are the first observational evidence for their existence. If our interpretation is correct, we are essentially seeing a planet caught in the act of formation.”
The NRL researchers will continue to examine the planet’s motion and get further data on the properties of the circumplanetary disk. They say that the baby planet and its disc will most possibly turn out to be veiled by the circumstellar disk in 2 years and will not come back for another 15 years.
