Examples

“For any rotating planetary body, there is a thermal limit beyond which the rotational velocity at the equator intersects the Keplerian orbital velocity. Beyond this corotation limit (CoRoL), a hot planetary body forms a structure, which we name a synestia, with a corotating inner region connected to a disk-like outer region.”

“For a brief time during its infancy, Earth was a hot, doughnut-shaped blob called a synestia. […] A synestia has an exterior region marked by clouds of molten rock and dust, all at a scorching 2000°C or hotter.”

“The investigation also examined the geochemical consequences of lunar formation resulting from the high-energy collision of proto-planets that created a huge, vaporized, doughnut-shaped object called a synestia.”
