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."

Yadgir: Dead bodies of boys who went grazing found in village stream
Yadgir: In a shocking incident reported from Devathkal village of Surapur taluk, two boys, Shreyanna (8) and Yuvaraja (9), who were grazing cattle, died of drowning on Sunday afternoon as they went for a bath in a stream nearby.
The boys had reportedly gone missing in the waters of the stream on Sunday afternoon. The family members found the boys’ clothes on the banks of the stream but, as their search for the boys proved futile, they brought the matter to the notice of the police and fire brigade.
The police team, led by Deputy Superintendent of Police Javed Inamdar and Inspector Anand Wagmode, along with the staff members of the fire brigade, searched for the missing boys on Sunday night, but failed to find the boys. The search was resumed on Monday morning and, at around 9 am on Monday, the bodies of both boys were found in the stream, sources have said.
A case has been filed by the Surapur Police and investigation is underway.
