太阳黑子与极磁斑的关联

The Association of Polar Faculae with Polar Magnetic Patches Examined with Hinode Observations

摘要:

利用2007年9月日出卫星对北极地区的分光偏振观测,研究了太阳极斑的磁特性。极性光斑嵌入几乎所有磁通量大于$10^{18}$ Mx的磁贴片中,而没有极性光斑的磁贴片在低于$10^{18}$ Mx的磁通量范围内占主导地位。光斑比它们的母斑小得多,并且单个磁斑包含单个或多个光斑。光斑通常具有比其母斑内的周围区域更高的固有磁场强度。由大的(${\ge}10^{18}$ Mx)浓度贡献的总磁通量中,只有不到20%是由相关的极光斑贡献的,已知这些浓度是由太阳周期调制的。

英文摘要:

The magnetic properties of the Sun's polar faculae are investigated with spectropolarimetric observations of the north polar region obtained by the Hinode satellite in 2007 September. Polar faculae are embedded in nearly all magnetic patches with fluxes greater than $10^{18}$ Mx, while magnetic patches without polar faculae dominate in the flux range below $10^{18}$ Mx. The faculae are considerably smaller than their parent patches, and single magnetic patches contain single or multiple faculae. The faculae in general have higher intrinsic magnetic field strengths than the surrounding regions within their parent patches. Less than 20% of the total magnetic flux contributed by the large (${\ge}10^{18}$ Mx) concentrations, which are known to be modulated by the solar cycle, is accounted for by the associated polar faculae.
