Oligarch

(term for large planetesimals that dominate)

Oligarch is a term used in the Planet Formation theory, Oligarch Theory, which theorizes that after formation of numerous Planetesimals, a stage follows when the larger ones tend to grow faster, called Runaway Growth. The resulting larger group are termed oligarchs, which tend to reduce the number of planetesimals through merging collisions and/or by flinging them out of the system, and their growth at this point takes on a slow phase, called Oligarch Growth.
