0 a circle of light around the sun or moon, visible especially during an eclipse -- korona
The temperature of the corona is a staggering one million degrees.
These results are useful for description of electron-beam propagation in the solar corona, which is a source of sporadic radiation.
At this stage, the wire remains in a liquid- solid phase with a low-density plasma corona.
The high-density pellet core is surrounded by a hot, fully ionized low-density corona.
Taking into account the absence of counteracting pressure in the corona plasma, it is possible to expect it pinching onto the cold core plasma.
Density measurements of the coronal plasma indicate that the fraction of the total initial mass contained in the corona increases as the wire diameter decreases.
In weakly deformed gneiss, the mafic minerals (biotite, augite and hornblende) occur as irregular clusters, locally separated from plagioclase by coronas of garnet.
The value of the corona inception voltage is readily deduced from the corresponding experimental data.
Flowers are pendulous with reflexed tepals and have a narrow floral tube with a prominent corona.
