条纹相对论风中相互作用电流片的成丝不稳定性:低西格玛的起源?
Filamentation Instability of Interacting Current Sheets in Striped Relativistic Winds: The Origin of Low Sigma?
摘要:
我概述了一种机制,类似于韦伯不稳定性的互穿梁,其中相邻的电流片在条纹风从一个倾斜的转子相互作用,通过两个流样的机制(韦伯不稳定性在平地),以创建一个异常的电阻率,加热片,并导致磁场扩散湮灭在风上游的终止冲击。这种加热会对从太阳能电池中可观测到的非脉冲发射产生影响。
英文摘要:
I outline a mechanism, akin to Weibel instabilities of interpenetrating beams, in which the neighboring current sheets in a striped wind from an oblique rotator interact through a two stream-like mechanism (a Weibel instability in flatland), to create an anomalous resistivity that heats the sheets and causes the magnetic field to diffusively annihilate in the wind upstream of the termination shock. The heating has consequences for observable unpulsed emission from pulsars.
