The Reiner Gamma swirl is a prime location to investigate the lunar albedo patterns and their colocation with magnetic anomalies. The precise relationship between impinging plasma and the swirl, and, in particular, how these interactions vary over the course of a lunar day, remains an open issue. Here we use a fully kinetic particle‐in‐cell code, coupled with a magnetic field model based on orbital‐altitude observations, and simulate the interaction with the Reiner Gamma anomaly for all plasma regimes the region is exposed to along a typical orbit, including different solar wind incidence angles and the Moon's crossing through the terrestrial magnetosphere. Consistent with the hypothesis that swirls form as a result of plasma interactions with near‐surface magnetic fields, we show that the energy flux profile produces a pattern similar to Reiner Gamma's alternating bright and darkly colored bands, but only when integrating over the full lunar orbit. We additionally show that including He as a self‐consistent plasma species improves the match.

模拟驯鹿伽马旋流：太阳风僵持的长期影响

Reiner Gamma旋流是研究月球反照率模式及其与磁异常的共址的主要位置。撞击的等离子体与漩涡之间的精确关系，尤其是这些相互作用在农历日过程中如何变化，仍然是一个悬而未决的问题。在这里，我们使用完全动力学的粒子内编码，并结合基于轨道高度观测的磁场模型，并模拟该区域沿典型轨道所暴露的所有等离子体状态与雷纳伽玛异常的相互作用。不同的太阳风入射角和月球穿过地球磁层的穿越。与等离子体与近地表磁场相互作用而形成漩涡的假设相一致，我们表明，能量通量剖面产生的图案类似于Reiner Gamma交替的明亮和深色带，但仅当在整个月球轨道上积分时才如此。我们还表明，包括他 因为自洽的血浆物质可以改善匹配度。
