Indian scientists led by Abhijit Chakraborty discover a sub-sized planet Saturn: Technology News, Firstpost



The Physical Research Laboratory (PRL), based in Ahmedabad, discovered a planet of sub-Saturn size or super Neptune (with a mbad equivalent to 27 Earths and size six times the radius of the Earth) around a star similar to the Sun, a official statement said on Thursday .

This discovery is very important to understand the mechanism of formation of such Super Neptune or sub-Saturn planets that are too close to the host star as well as planetary formations around Sun Stars, said the statement from the space agency.

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," he said.

 Telescope

The research paper appeared online in the Astronomical Journal of the American Astronomical Society.

The discovery was made by a team of scientists and engineers led by Abhijit Chakraborty measuring the mbad of the planet using the spectrometer "PRL Advance Radial-velocity-velocity Abu-sky Search" (PARAS) originally designed and integrated with a telescope 1.2 m at the Gurushikhar Observatory of the PRL in Mount Abu, India.

"Only 23 planetary systems (including this discovery) are known to date with mbades between 10 and 70 terrestrial mbades and sizes of 4 to 8 terrestrial radii with such a precise mbad measurement," the statement said.

"In addition, PARAS is the first of its kind of spectrograph in Asia that can measure the mbad of a planet by rotating around a star.There are very few spectrographs in the world that can make such precise measurements."
