Gujrat based lab discovers sub-Saturn size planet

Physical Research Lab (PRL) based in Gujrat have discovered a sub-Saturn or super-Neptune sized planet around a Sun like star. The team of scientists and engineers led by Prof. Abhijit Chakraborty discovered the planet which is 6 times the radii and 27 times the mass of Earth. The planet has been named EPIC 211945201b or K2-236b.

This discovery makes it 23rd planetary system known to man which has mass between 10-70 Earth mass and size of 4-8 radii of Earth. India, with this discovery, is among the select few countries which have discovered planetary systems beyond our own solar system.

PARAS (PRL Advance Radial-velocity Abu-sky Search)

This discovery was possible because of indigenously designed spectrograph PARAS which is has 1.2m telescope integrated into it, which measured the mass of the planet accurately. The spectrograph is located in PRL’s Gurushikhar Observatory in Mount Abu. PARAS is the first spectrograph in Asia which can measure the mass of an planet going around a star.
