英文摘要Most protons in the solar wind belong to one of two different populations, the less dense beam protons and the denser core protons. The beam protons, with a velocity of (1-2) V-A (V-A is the local Alfven speed), always drift relative to the core protons; this kind of distribution is unstable and stimulates several kinds of wave mode. In this study, using a 2D hybrid simulation model, we find that the original right-handed elliptically polarized Alfven waves become linearly polarized, and eventually become right-handed and circularly polarized. Given that linearly polarized waves are a superposition of left-handed and right-handed waves, cyclotron resonance in the right-handed/left-handed component heats beam/core protons perpendicularly. The resonance between beam protons and right-handed polarized waves is stronger when the beam relative density is lower, resulting in more dramatic perpendicular heating of beam protons, whereas the situation is reversed when the beam relative density is larger.
