Abstract

Based on the previously proposed steady-state 3D model of a solar facular knot, we have developed its modified version in which the solitary nature of the facular object is reflected: its magnetic field is sharply bounded in the radial direction. The facula temperature profile calculated for the steady state of such a magnetic structure is compared with the high-resolution filtergram taken in the photospheric TiO 7057 Å line at Big Bear Solar Observatory on June 19, 2017, at the New Solar Telescope (with a 1.6-m aperture). The image shows two closely spaced very dark micropores with a diameter \({\sim}300\) km each. The micropores are surrounded by a fan of thin, light, radially elongated fibrils resembling a sunspot penumbra. The theoretically calculated \(T\) profile of the facular knot completely reproduces these morphological features of the object being modeled.

孤眼结：喷泉磁结构和温度曲线

摘要

基于先前提出的太阳太阳眼结的稳态3D模型，我们开发了其修改版本，其中反映了太阳眼对象的孤立性质：其磁场在径向方向上有界。将为这种磁性结构的稳态计算的光斑温度曲线与2017年6月19日在大熊太阳能天文台的光球TiO 7057Å线中使用的高分辨率滤光片进行了比较，在新的太阳望远镜上（1.6 -m孔径）。该图显示了两个间距很近的非常暗的微孔，每个直径为\（{\ sim} 300 \） km。微孔被像黑子半影一样的细的，轻的，径向伸长的原纤维的扇形包围。理论计算的\（T \） 眼结的轮廓完全再现了要建模的对象的这些形态特征。
