India discovers sub-Saturn size planet
New Delhi, June 21: The Ahmedabad-based Physical Research Laboratory (PRL) has discovered a sub-Saturn or super-Neptune size planet (with mass equivalent to 27 Earths and size 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 formation 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 Sun-like stars, said the Space Department statement.
The planet will be known as EPIC 211945201b or K2-236b.
With this discovery, "India has joined a handful of countries which have discovered planets around stars beyond our solar system", it said.
The research work has appeared online in Astronomical Journal of the American Astronomical Society.
The discovery was made by a team of scientists and engineers led by Abhijit Chakraborty by measuring the mass of the planet using the indigenously designed "PRL Advance Radial-velocity Abu-sky Search" (PARAS) spectrograph integrated with 1.2m Telescope at PRL's Gurushikhar Observatory in Mount Abu, India.
"Only 23 such planetary systems (including this discovery) are known to this date with masses between 10 and 70 Earth mass and size of 4 to 8 Earth radii with such precise measurement of mass," the release said.
"Further, PARAS is the first of its kind spectrograph in Asia which can measure the mass of a planet going around a star. Very few spectrographs exist around the world that can do such precise measurements."

Karnataka Assembly bypolls victory: Shivakumar gives credit to CM Siddaramaiah's leadership
Bengaluru (PTI): Karnataka Deputy Chief Minister D K Shivakumar on Saturday gave credit to Chief Minister Siddaramaiah's leadership as well as the five guarantees for the Congress party’s success in the assembly bypolls.
Shivakumar said this victory was a prelude to the 2028 assembly election where the party would once again win.
The Congress won the Channapatna, Shiggaon and Sandur Assembly segments.
The by-elections were held on November 13 and the results were announced today.
The ruling Congress on Saturday retained its strong hold of Sandur, with its candidate E Annapoorna, winning the seat by defeating BJP's ST Morcha president Bangaru Hanumanthu.
In the Channapatna segment, Congress' C P Yogeeshwara won the high profile seat by defeating JD(S) candidate and Union Minister H D Kumaraswamy's son Nikhil Kumaraswamy.
Similarly, Congress' Yasir Ahmed Khan Pathan won the Shiggaon Assembly segment by defeating former Chief Minister Basavaraj Bommai's son Bharath Bommai.
"Our guarantees, Siddaramaiah’s leadership and our workers and MLAs are responsible for our victory," Shivakumar told reporters.
He said neither Nikhil Kumaraswamy nor Bharath Bommai lost the election. In fact, this was the defeat of their parents -Union Minister H D Kumaraswamy and BJP MP Basavaraj Bommai.
"With this victory, our tally has now gone up to 138. There are other numbers as well, but I will not spell out how some people have internally supported us," Shivakumar, who is also Congress state president, said.
The Karnataka Assembly has 224 seats.
The Deputy CM advised his opponents to focus on development works instead of making baseless allegations as it would fetch them nothing but a constant defeat.
