Study Sheds Light On Planetary Orbital Pile-Ups

Researchers said they have found why some orbits seen in young solar systems seem to be more popular than others. Astronomers have been puzzled as to why giant gas planets like Jupiter and Saturn appear to occupy certain regions in mature solar systems while staying clear of others. Ilaria Pascucci, an assistant professor at the University of Arizona's Lunar and Planetary Laboratory, said the final distribution of planets does not vary smoothly with distance from the star, but has clear...

Astronomers have observed neon in disks of dust and gas swirling around sunlike stars for the first time. University of Arizona astronomers who collaborated in the observations say that neon could show which stars retain their surrounding dust-and-gas disks needed to form planets and which stars might already have formed planets. "When I saw the neon, I couldn't believe it. I was just amazed," said UA Steward Observatory astronomer Ilaria Pascucci. "We were not expecting to see neon around...

Gas-giant planets like Jupiter and Saturn form soon after their stars do, according to new research. Observations from NASA's Spitzer Space Telescope show that gas giants either form within the first 10 million years of a sun-like star's life, or not at all. The study offers new evidence that gas-giant planets must form early in a star's history. The lifespan of sun-like stars is about 10 billion years. Ilaria Pascucci of the University of Arizona Steward Observatory in Tucson led a team of...
