The Sun’s extremely hot outer layer, the corona, has a very different chemical composition from the cooler inner layers, but the reason for this has puzzled scientists for decades.
One explanation is that, in the middle layer (the chromosphere), magnetic waves exert a force that separates the Sun’s plasma into different components, so that only the ion particles are transported into the corona, while leaving neutral particles behind (thus leading to a build-up of elements such as iron, silicon and…
