Modeling the Spectrum of the K-corona with Embedded Streamers
Abstract
The white light emission from the corona is generated by the Thomson scattering of photospheric emission by electrons. Recently Reginald and Davila (Solar Phys, 2000) have developed models, assuming a radially symmetric coronal electron density, that suggest that spectral measurements of the K-coronal emission can be used to determine the electron temperature, and the radial outflow velocity of electrons in the low corona. These measurements could provide for continuous remote-sensing observation of the solar wind speed from a spacecraft located at say L1. Recently these models have been extended to include the effect of streamers. Streamers are modeled simply as localized density enhancements along the line of sight. During this paper, the results of these models will be discussed, and the effect on the measurement of electron temperature and velocity will be assesed. Experimental efforts to verify these model predictions will be discussed in a separate paper also presented at this meeting.
