A team of scientists and engineers from the Physical Research Laboratory (PRL), Ahmedabad, has discovered a sub-Saturn or super-Nut planet around a star similar to the Sun. The planet discovered by the directed team by Prof. Abhijit Chakraborty for PRL will be known as EPIC 211945201b or K2-236b. The mass of the new planet is around 27 mass of the Earth; and its size approximately six radii of the Earth.

The discovery gains importance as it helps scientists understand the mechanism of formation of such Super Neptune or sub-Saturn planets, which are too close to the host star and also as planetary formations around sun-like stars. [19659006] The official statement said that it was made by measuring the mass of the planet using the spectrometer "PRL Advance Radial-Velocity Abu-sky Search" (PARAS) originally designed and integrated with a 1.2 m telescope. at the Gurushikhar Observatory of the PRL in Mount Abu, India.

"So far 23 planetary systems (including this discovery) are known with masses between 10 and 70 landmasses and sizes of 4 to 8 terrestrial radii with such a precise measurement of mass," the statement said.

With this discovery, India has joined a handful of countries, which have discovered planets around stars beyond our solar system. In addition, PARAS is the first spectrograph of its kind in Asia, which can measure the mass of a planet that revolves around a star. There are very few spectrographs in the world that can make such precise measurements, the statement adds.

The research work has also been published in the Astronomical Journal of the American Astronomical Society.
