An article published in the journal “Nature” reports a study on the exoplanet cataloged as TIC 241249530 b which labels it as a progenitor of a hot Jupiter. A team of researchers used various telescopes to study TIC 241249530 b and try to understand its characteristics and evolution. This gas giant has an extremely eccentric orbit, meaning it’s extremely elongated, which could change greatly as time passes.

Observations and simulations suggest that the star’s gravitational action will drive this planet to have an almost circular orbit close to the star itself. This led the researchers to conclude that TIC 241249530 b is in the first phase of a planetary migration. The star is slightly more massive than the Sun and has an age estimated at just over three billion years, which indicates that these processes can begin well after the formation of a planetary system.
