Dynamical evolution of Haumea collisional family: Clues on the collision physics, new family members and implications for the outer solar system
Abstract
Recently, the first collisional family consisting of Haumea and other nine trans-neptunian objects (TNOs) was identified in the trans-neptunian belt. Here, we modeled the long term orbital evolution of an ensemble of family fragments over 4 Gyr. We obtained collisional families (with ~60-75% survival rate) that reproduced the currently known Haumea's family. These objects concentrated in wide regions of orbital elements in the belt and populated the four main dynamical classes of TNOs (classical, detached, resonant and scattered). In addition, the great majority of fragments displayed negligible long term orbital variations, implying that the orbital distribution of the intrinsic Haumea's family can constrain the orbital conditions and physics of the collision that created the family billions of years ago.
