"Surprising Discovery: Old Stars Lack Hot Jupiters"
A new study suggests that hot Jupiters, large gas giants that orbit their star in a matter of days, are rare around middle-aged Sun-like stars. The study analyzed a sample of 382 Sun-like stars and found that younger stars were more likely to have hot Jupiters than older stars. The researchers propose that hot Jupiter orbits destabilize over time, causing them to eventually be consumed by their star. This explains why our solar system, which is still in its middle age, does not have a hot Jupiter. The study highlights the uniqueness of our solar system and the need to explore a wider range of planetary systems to better understand the occurrence of different types of exoplanets.
