月球作为一个既没有全球性磁场又没有明显大气层的星体，一直以来都认为太阳风是直接作用在月球向阳面且被完全吸收。然而近年来，越来越多的观测与模拟结果表明，太阳风与月表的相互作用由于月表局地磁异常的存在而出现一些”例外”，在一定条件下，可以形成月表微磁层（LMM）。
Analysis of 3D MHD Instability of Antisolar Latitudinal Differential Rotation in F, G and K stars
Analysis Instability Latitudinal Differential Rotation

2011/10/8
Motivated by observations that only a very few stars have been found to have antisolar differential rotation, much weaker in amplitude than that of the Sun, we analyze the stability of antisolar and s...
