A cosmic barbecue: Researchers spot 60 new 'hot Jupiter' candidates
New Haven CT (SPX) Jul 07, 2017
Yale researchers have identified 60 potential new "hot Jupiters" - highly irradiated worlds that glow like coals on a barbecue grill and are found orbiting only 1% of Sun-like stars. Hot Jupiters constitute a class of gas giant planets located so close to their parent stars that they take less than a week to complete an orbit. Second-year Ph.D. student Sarah Millholland and astronomy professor Greg Laughlin identified the planet candidates via a novel application of big data techniques. They used ... read more
