In an epic Indian discovery, a team from the Physical Research Laboratory, Ahmedabad, has first seen a planet six times larger than the Earth and rotating around a star similar to the Sun at about 600 years distance light. Both the planet and the star were named EPIC.
EPIC A New Planet Discovered By Scientists
The PRL team has found a sub-Saturn or super-Neptune size planet. The team was led by Professor Abhijit Chakraborty of PRL, Ahmedabad.
The PRL Team Who Discovered The New Planet
The team found the planet is smaller than Saturn and larger than Neptune. Its mass is about 27 times the Earth and six times that of the Earth at the radius. Scientists estimate that over 60% of its mass could consist of heavy elements such as ice, silicates and iron.
“PRL Advance Radial Velocity Abu-Sky Search”
The discovery of the new planet was made by measuring the mass of the planet using the indigenously designed “PRL Advance Radial-velocity Abu-sky Search” (PARAS) spectrograph.
The spectrograph is the first of its kind in the country able to measure the mass of a planet that revolves around a star, all over the world (especially in the United States and in Europe) that can make such precise measurements, “said the space agency on its website at the end of June 8
“With this discovery, India has joined a handful of countries that have discovered planets around the stars,” announced the PIndian Space Research Organization.
PRL is mainly supported by the Department of Space, whose arm is ISRO. Significantly, the discovery was made using a spectrograph designed by PRL, PARAS, to measure and confirm the mass of the new planet.
Scientists have observed the goal for 420 days or about 1.5 years. They measured the mass of the planet using the PRL Advance Radial-velocity Search or the PARAS Spectrograph integrated with the 1.2-meter telescope located at the PRL Observatory Gurushikhar in Mount Abu, Rajasthan.
This discovery is important for understanding the mechanism of formation of such super-Neptune or sub-Saturn type of planets that are too close to the host star. The detection also adds a sparse catalogue of 22 other confirmed exoplanet systems that have a mass and a ray in this range, said ISRO.
EPIC was found by turning very close to the Sun-like star, turning around it once in about 19.5 days and is unlikely to be habitable due to its high surface temperature of about 600 ° C.
The new planet has a mass of about 27 Earth Mass and size of 6 Earth Radii. The exoplanet was found around a Sun-like star and goes around the star in about 19.5 days.
According to the Indian scientists who found this new planet, the surface temperature of the planet is around 600 degrees Celsius given the fact that it is very close to the host star, which is to say that the new planet is 7 times nearer than the host star.
Discoveries like these have many potential benefits for future advances as well. They could pave the way for a more efficient mechanism and advanced equipment that can discover habitable planets and who knows, even life.
