The Ahmedabad-based Physical Research Laboratory (PRL) has discovered a sub-Saturn or super-Neptune size plane (with a mass corresponding to 27 soils and magnitude six times of Earth's radius) around a sun-like star, an official statement said on thursday .
This discovery is very important for understanding the forming mechanism of such super-Neptune or sub-Saturn kind of planets that are too close to the host star and as well as planet formations around
The planet will be known as EPIC 211945201b or K2-236b.
With this discovery, "India has joined a handful of countries that have discovered planets around stars beyond our solar system," said it.
The research work has appeared online in the Astronomical Journal of the American Astronomical Society.
The discovery was made by a team of researchers and engineers led by Abhijit Chakraborty by measuring the mass of the planet using the in-house "PAR spectrum" for the PRL Advance Radial Speed Abu Sky Search (PARAS) integrated with 1.2m telescope at PRL's Gurushikhar Observatory in Abu Abu, India.
"Only 23 such planetary systems (including this discovery) are known for this date with masses between 10 and 70 earthquakes and 4 to 8 earthquakes size with such accurate mass measurement," said the release.
"PARAS is furthermore the first of its Kindly spectrograph in Asia that can measure the mass of a planet that goes around a star. Very few spectrographs exist around the world that can make such accurate measurements. "
