Using advanced new simulations, a team of astronomers in the U.S. has developed a promising new theory for how giant, gaseous exoplanets migrate into stiflingly close orbits around their host stars. Led by J. J. Zanazzi at The Pennsylvania State University, the team showed how both massive \u201chot Jupiters\u201d and smaller, Neptune-sized planets could migrate from distant, elliptical orbits as they release energy via dramatic shock waves in their outer atmospheres. Their results have been published<\/a> in The Astrophysical Journal.<\/p>\n

Hot Jupiters are a class of exoplanets with masses comparable to the largest planet in our own solar system, but which orbit extremely close to their host stars\u2014imparting them with temperatures that can exceed some 2,000 Kelvin. Not only are their orbital periods extremely short, they also cluster within a window between three and five days: a phenomenon dubbed the \u201chot Jupiter pileup.\u201d<\/p>\n

Similar clustering can also be seen in smaller gas giants, with masses between those of Neptune and Saturn, known as the \u201cNeptune ridge.\u201d Yet unlike hot Jupiters, these planets are strikingly scarce on orbits shorter than about three days, creating a stark observational gap named the \u201cNeptune desert.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
