Young planets interact with their parent gas disks through tidal torques. An imbalance between inner and outer torques causes bodies of mass 0.1 Earth masses (M ⊕) to lose angular momentum and migrate inward rapidly relative to the disk; this is known as " Type I " migration. However, protoplanets that grow to gas giant mass, O(10 2) M ⊕ , open a gap in the disk and are subsequently constrained to migrate more slowly, locked into the disk's viscous evolution in what is called " Type II… CONTINUE READING
