The solar X-ray corona

Astrophysics and Space Science, 1996
The solar corona, and the coronae of solar-type stars, consist of a low-density magnetized plasma at temperatures exceeding 106 K. The primary coronal emission is therefore in the UV and soft x-ray range. The observed close connection between solar magnetic fields and the physical parameters of the corona implies a fundamental role for the magnetic ...

Optical Obsdervations of the Solar Corona

Space Science Reviews, 1982
The history of optical observations of the solar corona is traced through the development of lour topics: the observation of naturally occurring total solar eclipses, the discovery of forbidden emission lines in the solar corona, the development of narrow spectral bandpass observing techniques, and the invention of the coronagraph.

Cyclotron Heating of the Solar Corona

Astrophysics and Space Science, 1998
A physical model of the solar transition region and corona is presented, in which plasma flows in rapidly-diverging coronal funnels and holes are described within the framework of a two-fluid model including wave-particle interactions. The ions are heated by wave dissipation and accelerated by the pressure gradient of high-frequency Alfven waves, which

Waves and Turbulence in the Solar Corona

2004
In the solar corona (and solar wind) waves and turbulence occur at all scales ranging from the particles’ gyroradii to the size of a solar radius (or even to an astronomical unit). A concise review of some new observations and theories of waves in the sun’s atmosphere and corona is given, with the focus being on coronal waves that are magnetically ...
