Predicting Ly-α intensities in coronal streamers.
Abstract
In the near future, SOHO UVCS will make long-term observations of coronal streamers in UV lines, providing a new tool for the analysis of structures which have been known for decades but are still far from being adequately described. The purpose of this work is to evaluate the Ly-α brightness of coronal streamers, adopting the streamer models obtained, via a time-dependent numerical relaxation technique, by Wang et al. This allows both to understand the role of geometric vs. physical factors in determining the streamer Ly-α intensity and to provide guidelines for UVCS observational operations. Future prospects along this line of research are also briefly summarized.
