Indian lab discovers large exoplanet around a Sun-like star

NASA's Kepler satellite, which was launched in 2009 as part of the K2 mission, has uncovered three Earth-sized planets in another solar system. With this, India joins the elite club of countries that have discovered planets.

The star the planets orbit is located in the constellation of the Sextant at 50 parsecs from the Sun - that means it's about 160 light years away.

"Although the atmospheric temperature of red dwarf stars, around which these planets revolve, is 3,450 and 3,800 Kelvin respectively, nearly half the temperature of our Sun", the researchers said. Now, a trio of new rocky worlds has been discovered orbiting a distant star, and while they're a lot like Earth in terms of size, they're a bit steamier. They integrated the spectrograph with a 1.2m telescope at PRL's Gurushikar Observatory in Mount Abu, to measure the mass of the planet, leading to the discovery.

Ahmedabad, India, have identified a new exoplanet, a super-Neptune planet, situated at 600 million light-years far from the Earth.

Importantly, this discovery could help scientists understand how these types of planets form so close to their host star.

Otherwise, the planets are probably inhospitable: they are very close to their star and therefore very warm. The detection also adds to a sparse catalogue of 22 other confirmed exoplanet systems that have a mass and radius in this range, ISRO said. Isro said very few such spectrographs exist around the world (mostly in the United States and Europe) that can do such precise measurements. Orbited by two super-earths that are larger than the size of our planet two times, and mass - five.

The universe keeps puzzling and intriguing curious humans as they persist in their hunt for habitable planets.

EPIC was found circling very close to the Sun-like star, going around it once in about 19.5 days and unlikely to be inhabitable because of its high surface temperature of around 600°C.

Based on the mass and radius, model-dependent calculations suggest that the heavy elements, like ice, silicates, and iron content is 60 to 70% of the total mass. The PRL scientists observed the target over a time-baseline of 420 days (in about 1.5 years) using the PARAS spectrograph for probing the nature of the system.
