Coronae develop when a mantle upwelling bends the crust upwards, which later collapses when the dynamic support from the upwelling is lost, resulting in a shallow oval-shaped depression.
Coronae are conventionally named for goddesses: however when it was first discovered it was thought to be a crater, and named accordingly.
It is the female equivalent to hirsuties coronae glandis.
Coronae differ from haloes in that the latter are formed by refraction (rather than diffraction) from comparatively large rather than small ice crystals.
They are usually associated with coronae and "tesserae".
It seems that only some giants, and very few supergiants, possess coronae.
The angular size of the corona depends on the diameters of the cloud droplets - small droplets produce large coronae.
Other structural features are observed in coronae and coronae-like features as well as tesserae and other highly tectonized units.
