Solar wind charge-exchange (SWCX) emission is present in every X-ray observation of an astrophysical object. The emission is problematic when one cannot remove the foreground by the simultaneous measurement of a nearby field. SWCX emission is a serious impediment to the study of the diffuse hot ISM, including the galactic halo, as its contribution to diagnostic emission lines is temporally variable. Modeling the SWCX emission, in order to remove it from our observations, has proven to be more difficult than originally anticipated. This work reviews our current understanding of SWCX emission, with special attention to all the components required for future modeling tools. Since, in the absence of such a tool, observing programs can still be constructed to minimize the effect of SWCX, mitigation strategies are discussed. Although some aspects of SWCX will be very difficult to characterize, progress continues on many fronts.

太阳风电荷交换：天体物理学上的麻烦

太阳风电荷交换 (SWCX) 发射出现在对天体物理物体的每次 X 射线观测中。当人们不能通过同时测量附近的场来去除前景时，发射是有问题的。SWCX 发射是研究漫射热 ISM 的严重障碍，包括银河晕，因为它对诊断发射线的贡献是随时间变化的。对 SWCX 发射进行建模，以便将其从我们的观察中去除，已证明比原先预期的更困难。这项工作回顾了我们目前对 SWCX 发射的理解，特别关注未来建模工具所需的所有组件。由于在没有这样的工具的情况下，仍然可以构建观测计划来最小化 SWCX 的影响，因此讨论了缓解策略。
