Computer Simulations Shed New Light on Gas Giant Formation astronomy space science
Solar system’s gas giants, such as Jupiter, Saturn, and massive exoplanets, were formed via the gas accretion onto the solid cores, each with a mass of roughly 10 Earth masses. However, rapid migration due to disk-planet interaction prevents the formation of such massive cores via accretion of planetesimals. Comparably rapid core growth via pebble accretion requires very massive protoplanetary disks because most pebbles fall into the central star.
“This is a problem, because gas giants play huge roles in the formation of potentially habitable planets within planetary systems.” “The new program is able to handle celestial bodies of all sizes and simulate their evolution via collisions,” Dr. Kobayashi said.
