Abstract

The Rotation Period of Hi’iaka, Haumea’s Largest Satellite

Using relative photometry from the Hubble Space Telescopeand Magellan, we have found that Hi’iaka, the largest satellite of the dwarf planet Haumea, has a rotation period of ~9.8 hours. This surprisingly short period, ~120 times faster than its orbital period, creates new questions about the formation of the Haumea system and possible tidal evolution.
