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.

天体物理物体的每次 X 射线观测中都存在太阳风电荷交换 (SWCX) 发射。当无法通过同时测量附近场来消除前景时，发射就会出现问题。 SWCX 发射严重阻碍了包括银河晕在内的弥漫热 ISM 的研究，因为它对诊断发射线的贡献是随时间变化的。事实证明，对 SWCX 排放进行建模以将其从我们的观测中删除，比最初预期的更加困难。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以尽量减少 SWCX 的影响，因此讨论了缓解策略。尽管 SWCX 的某些方面很难描述，但许多方面仍在继续取得进展。
