颗粒间非常小的太阳磁结构的热弛豫:产生kG磁场强度的过程
Thermal relaxation of very small solar magnetic structures in intergranules: a process that produces kG magnetic field strengths
摘要:
在颗粒间环境中,非常小的磁通量管的平衡组态自动产生千吉磁场强度。我们认为,这样的过程发生在太阳和补充的对流坍缩(CC),这是传统上调用来解释的kG磁浓度在太阳光球的形成。特别是,它可以集中非常弱的磁通量揭示了新的红外光谱偏振仪,其中的操作的CC可能有困难。作为论证的一部分,我们证明了太阳磁场的存在,即非常弱的通量,但磁场集中(约3 x 10^{16} Mx和1500 G)。
英文摘要:
The equilibrium configuration of very small magnetic fluxtubes in an intergranular environment automatically produces kG magnetic field strengths. We argue that such process takes place in the Sun and complements the convective collapse (CC), which is traditionally invoked to explain the formation of kG magnetic concentrations in the solar photosphere. In particular, it can concentrate the very weak magnetic fluxes revealed by the new IR spectro-polarimeters, for which the operation of the CC may have difficulty. As part of the argument, we show the existence of solar magnetic features of very weak fluxes yet concentrated magnetic fields (some 3 x 10^{16} Mx and 1500 G).
