摘要:

The properties of minor ions in the low solar corona are studied on the basis of a quasi‐hydrostatic equilibrium model suitably modified to account for the combined effects of Coulomb friction and Alfven wave acceleration in dragging minor ions out of the corona against the binding solar gravitational force. The analysis therefore generalizes the work of Hollweg (1981) to include the effect of waves which become important in the upper corona and the results, which must be treated with some caution, indicate that provided the proton flux is sufficiently large, the ions are evicted from the corona into the wind at the same speed as the protons with relative abundances which reflect their flux relative to protons in the low coron
