INVESTIGATION OF DIELECTRONIC RECOMBINATION SATELLITE EMISSION TO Fe XVIII FOR TEMPERATURE MEASUREMENTS OF STELLAR ATMOSPHERES

摘要

Dielectronic recombination satellite emission to the Fe XVIII and Fe XIX L-shell spectra have been investigated using collisional-radiative modeling of X-ray transitions near 14 ?. Although weak, such L-shell emission may be of interest for future temperature measurements of cool stars. The diagnostic has been evaluated using X-ray data from the Capella system measured by the Chandra X-Ray Observatory.
