Exospheric solar wind charge exchange as seen by XMM-Newton?

摘要

We review a selection of recent papers describing solar wind charge exchange emission occurring in the Earth's exosphere as seen by the X-ray observatory XMM-Newton. We discuss the detection of this emission, the occurrence with respect to the solar cycle and solar activity, and various spectral signatures observed. We also describe a model developed to predict the X-ray signal from exospheric charge exchange as would be detected by XMM-Newton, given the upstream solar wind conditions obtained from in situ solar wind monitors (? 2012 WILEY-VCH Verlag GmbH & Co.
