Discovery of three warm Jupiters: New gas giants TIC 147027702 b, TIC 245076932 b, and TIC 87422071 b

Star system: TIC 245076932 | Distance from the Sun: 1026 light years

Astronomers have successfully characterized three new 'warm Jupiters'—gas giant planets similar in size to Jupiter but with much longer orbits than the typical 'hot Jupiters' found close to their stars. 

Using data from the TESS space telescope and the new PLATOSpec instrument, the team identified TIC 147027702 b, which orbits its star every 44 days; TIC 245076932 b, a planet with a notably oval-shaped, eccentric orbit and a 21-day period; and TIC 87422071 b, a more massive giant orbiting every 11 days. These findings are crucial for understanding how massive planets form and move within their solar systems over time, providing rare examples of giants that do not sit right next to their host stars.
