Bright achievement of Indian astronomers: Exoplanet 13 times bigger than Jupiter discovered


- This exoplanet is 731 light years from Earth : completes one orbit around the parent star in just 7.24 days : temperature 1396 degrees Celsius

Ahmedabad/Mumbai: An international research team led by astronomers from the Physical Research Laboratory (PRL--Ahmedabad), an associate organization of the Indian Space Research Organization (ISRO), has discovered a giant exoplanet (Solar System) 13 times more massive than Jupiter, the giant planet of our solar system. An extraterrestrial planet called an exoplanet) has been a brilliant success.

The international research team led by PRL Senior Astronomer Professor Abhijit Bhattacharya includes astronomers from India, Germany, Switzerland and America.

Indian astronomers have succeeded in finding three such exoplanets so far. A paper on the discovery of this new exoplanet has been published in the journal Astronomy and Astrophysics Letters.

Sources in ISRO informed that an international team of astronomers has used the PRL Advanced Radial-Velocity Abu-Sky Search Spectrograph (PA) at PRL's Mount Abu's Gurushikhar Observatory to find the exoplanet, designated TOI 4603 b (or HD245134 b). .RS-Paras) has used a modern scientific device.

The surprising factor is that this extrasolar planet completes the orbit of its parent star in just 7.24 days. That is, one day of this exoplanet is very short. Also, this exoplanet is very close to its parent star. Also, the daytime temperature of this exoplanet is a super-boiling 1396 degrees Celsius. That is, this planet outside the solar system is a huge boiling furnace.

This exoplanet is located at a distance of 731 light years from Earth. Extensive research and studies have proven that this exoplanet has a mass (mass) of 14 g/cm3, which is 11 to 16 times more than the total mass of Jupiter, the largest planet in our solar system. The total mass of Jupiter is 1.8982 t 1027 kg.

ISRO sources also gave information that at the initial stage, the Transiting Exoplanet Survey Satellite (TESS) of the National Aeronautics and Space Administration (NAS) of America announced that this exoplanet was an unknown star.

Astronomers from all over the world have discovered more than 5,000 such exoplanets outside our solar system in search of life on any planet other than our Earth.

The peculiarity of this bird is that it can fly up to 10,000 km in a single flight. During a long life span of 8 to 20 years, it flies about 3 lakh km. With the flying power of the albatross, London's marine explorers want to catch pirates. The albatross is a special type of bird that can also protect ships if trained. Thus there is an armed force to protect the ship but often the pirates do not even let the smell of attack come to the security but now they will not be able to escape from the albatross. Sea food and especially fishing is a big business in the sea. When fishermen set their nets to catch fish, they catch fish as well as sea creatures and birds.
