Danielle Hastings (UCLA): Using relative photometry from the Hubble Space Telescope and 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.
David Jewitt (UCLA): I will present observations suggesting the role of rotational disruption in the solar system.
