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.
The fact that a fluid model must be used to describe the corona and solar wind does not imply that kinetic models are not needed.
In other words, we anticipate that in the low corona there are newly created ions due to continuous ionization of neutral particles.
The decreasing frequency indicates that the radiation source travels outward in the solar corona into regions of lower electron density and therefore smaller plasma frequency.
The simulations of interest are hohlraum plasmas in the case of indirect drive or the plasma corona for direct drive.
Here, the igneous and corona textures are obliterated by the growth of amphibolite-facies assemblages with hornblende, plagioclase, biotite, garnet and zoisite.
Figure 6 shows a comparison of the experimental core and corona expansion velocities with points taken from the simulated diagnostic images.
Once the magnetic field generated by the rising current becomes large enough, the low-density corona begins to self-pinch onto the core.
Flowers are pendulous with reflexed tepals and have a narrow floral tube with a prominent corona.
