Context

• A new warm Jupiter exoplanet with the highest density known till this date and mass 13 times than that of Jupiter, has been discovered by an international team of scientists at the Exoplanet Research Group of the Physical Research Laboratory (PRL), Ahmedabad.

Key Details about the explanet

• An exoplanet is any planet beyond the solar system and the one discovered by scientists from India, Germany, Switzerland and the U.S. is with a density of ~14 g/cm3.

  

• Massive giant exoplanets are those having mass greater than four times that of Jupiter.
• The Indian Space Research Organisation (ISRO) said that the discovery of this massive exoplanet was made using the indigenously made PRL Advanced Radial-velocity Abu-sky Search spectrograph (PARAS) at the 1.2 m telescope of PRL at its Gurushikhar Observatory in Mt. Abu by measuring the mass of the planet precisely.
• The newly discovered exoplanet was found around the star called TOI4603 or HD 245134.
• NASA’s The Transiting Exoplanet Survey Satellite initially declared TOI4603 as a possible candidate to host a secondary body of unknown nature.
• Massive giant exoplanets are those having mass greater than four times that of Jupiter. The newly discovered exoplanet TOI 4603b is one of the most massive and densest giant planets that orbits very close to its host star at a distance less than 1/10th the distance between our Sun and Earth.
• The exoplanet with a surface temperature of 1670 K is likely undergoing high-eccentricity tidal migration with an eccentricity value of approximately 0.3.
• The detection of such systems provides valuable insights into the formation, migration, and evolution mechanisms of massive exoplanets.
