Giant Planets Rarely Survive Their Host Star's Aging Process

In a recent study, researchers have made a groundbreaking discovery about the fate of giant planets orbiting close to Sun-like stars. According to a report on Earth. com, a new study suggests that these planets rarely survive their host star's aging process. As stars evolve and begin to swell, nearby worlds often vanish, drawn inward and destroyed by intense tidal forces.

The research, led by Dr. Edward Bryant at University College London and the University of Warwick, analyzed nearly half a million stars and found that only about 0. 28 percent, or roughly one in every 350, still host a close-in giant planet. This study, also reported on Earth. com, identified 130 planets and candidates, including 33 new discoveries, all orbiting stars nearing or in the red giant phase.

Dr. Bryant's research focuses on exoplanet populations and how stellar evolution reshapes planetary systems. His team's findings reveal that as stars move deeper into the red giant phase, a swollen, cooling late stage of Sun-like stars, nearby giants show up far less often. The occurrence rate of these planets drops significantly, from about 0. 28 percent in younger evolved stars to about 0. 11 percent in the coolest, puffed-up stars.
