ELECTRON DENSITY AND TEMPERATURE IN A STREAMER DERIVED FROM THE H-LY EMISSION

摘要

In this work we determine the electron temperature and density along an equatorial streamer observed in 1997. These quantities are obtained by comparing the H-Ly-α and H-Ly-β emissions in the streamer. For this work we used spectroscopic data from SOHO/UVCS, from 1.2 to 1.5 solar radius of observed heliocentric distance.
