Synestia, a New Type of Planetary Object

From UC Davis: Three-Minute Egghead podcastSarah Stewart and Simon Lock talk about synestias. A synestia is a new type of planetary object, they proposed, formed when a giant collision between planet-size objects creates a mass of hot, vaporized rock spinning with high angular momentum. Synestias could be an important stage in planet formation, and we might be able to find them in other solar systems.
