gravity darkening

== English == === Noun === gravity darkening (uncountable) (physics, astronomy) The phenomenon of a star rotating so rapidly that it is oblate, with a larger radius and thus lower surface gravity at the equator (which is thus cooler and darker: gravity-darkened), and higher surface gravity at the poles (which are hotter and brighter: gravity brightened). ==== Synonyms ==== gravity brightening === See also === limb darkening, limb brightening
