Spectroscopic diagnostics - general
Spectroscopic diagnostics of stellar
transition regions and coronae in the
XUV: AU Mic in quiescence
Del Zanna, G., Landini, M., & Mason, H. E. 2002, A&A 385, 968-985
This is a review paper on spectroscopic diagnostic techniques
that can be applied to XUV observations of active stars, including the
Sun.
In particular,
I discuss methods for the determination of electron densities, emission
measures and the chemical composition of the stellar transition regions
and coronae.
Severe limitations to some of the commonly used methods
and atomic data are highlighted.
New results, significantly different from those of the prvious
literature are found.
In particular, in terms of transition region densities,
where values one order of magnitude lower are found.
For the first time, it shown that the anomalous behavior of
the ions of the Li- and Na-sequence is also present for the stars.
