An international team of scientists has discovered two giant exoplanets orbiting the orange dwarf star known as TOI-4600, using the TESS orbiting telescope.
Scientists explained that one of these two planets makes a complete revolution around the star in a record period of 482 days.
Astronomers from Princeton University, USA, stated that this discovery confirms the possibility of using the TESS telescope to search for exoplanets that are very far from stars.
They pointed out that the discovery of these two planets greatly expands the possibility of applying the transit technique, which is the main method for discovering exoplanets, as scientists follow the changes in the light radiation of stars when planets pass in front of them.
The orbiting telescope TESS observed the star five times and recorded several periodic decreases in its brightness associated with the passage of two large planets, TOI-4600b and TOI-4600c. The first is a planet larger than Neptune and orbits the star in 83 days, while the second planet is similar to Saturn in size and takes 482 days to complete. complete orbit around the star.
Scientists stated that both planets are much closer in terms of temperature to Saturn and other giant gas planets in the solar system, which makes their study more interesting than the hundreds of hot Jupiters that were discovered during the past decade and a half at close distances to stars.
According to scientists, studying these planets in more detail will be available to astronomers next October, when TOI-4600c will pass again through the star’s disk, and the new measurements will help them check the orbital specifications of this gas giant and its mass, and obtain the first information about its formation and appearance using an observatory. Another orbiter, the JWST Telescope.
