Using data from NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton spacecraft, astronomers have looked for the effects of massive, close-in planets called hot Jupiters on their host stars that reside in binary stellar systems. Their results, published in the Monthly Notices of the Royal Astronomical Society, show that hot Jupiters can make their host star act younger than it is by causing the star to spin more quickly than it would without...
