Context: A new Jupiter-size exoplanet with the highest density known to this date and mass 13 times that of Jupiter, has been discovered by ISRO.
- The discovery of this massive exoplanet was made using the indigenously made PRL Advanced Radial-velocity Abu-sky Search spectrograph (PARAS).
- The newly discovered exoplanet is found around the star called TOI4603 or HD 245134.
- NASA’s Transiting Exoplanet Survey Satellite (TESS) initially declared TOI4603 as a possible candidate to host a secondary body of unknown nature.
- It is located 731 light years away. It orbits a sub-giant F-type star TOI4603 every 7.24 days.
What sets this discovery apart is that the planet falls into the transition mass range of massive giant planets and low-mass brown dwarfs with masses ranging from 11 to 16 times the mass of Jupiter. Only fewer than five exoplanets are currently known in this mass range so far.
About PARAS:
The PRL optical fibre-fed high-resolution cross-dispersed echelle spectrograph (Prl Advanced Radial-velocity Abu-sky Search), was commissioned at the Mount Abu 1.2 m telescope in India in 2012.
