【摘要】：太陽不斷地產(chǎn)生能量并通過電磁輻射等方式向外傳遞信息�？茖W(xué)家根據(jù)這些有限信息,從整體思考、簡化細(xì)節(jié),反推得到太陽的能源機(jī)制、結(jié)構(gòu)等物理信息,并根據(jù)實際觀測反饋驗證這些推理的正確性。對太陽這個復(fù)雜巨型系統(tǒng)的研究不但對天文學(xué)、物理學(xué)有重要的意義,也處處反映了系統(tǒng)科學(xué)中反饋、整體思想在太陽物理中的重要作用。太陽黑子中的亮橋(Light Bridges, LBs)是一個十分有趣的結(jié)構(gòu),盡管它已經(jīng)被詳細(xì)研究了幾十年,然而關(guān)于它的形成、演化、消失、磁場結(jié)構(gòu)以及與其他太陽活動的關(guān)系等方面還存在很多的問題。運動磁結(jié)構(gòu)(Moving Magnetic Features, MMFs)是另外一種與太陽黑子有關(guān)的結(jié)構(gòu)。它通常被描述為從黑子半影出現(xiàn),并快速向黑子外圍的網(wǎng)絡(luò)磁場區(qū)域運動。作為太陽表面的一種基本磁結(jié)構(gòu),運動磁結(jié)構(gòu)在太陽活動區(qū)的衰退中起著重要的作用,然而關(guān)于它的形成原因還存在很多未知問題。所有的這些與太陽黑子有關(guān)的問題都亟待解決,任何為研究亮橋、運動磁結(jié)構(gòu)等與太陽黑子結(jié)構(gòu)相關(guān)的現(xiàn)象而投入的努力都是十分有意義的,它們對理解太陽活動機(jī)制有著巨大的幫助。在Hα觀測中,拱狀暗條系統(tǒng)(arch filament systems, AFSs)通常被認(rèn)為是磁通量浮現(xiàn)區(qū)(emerging flux region, EFR)在色球?qū)拥谋憩F(xiàn)。目前,它與黑子周邊的運動磁結(jié)構(gòu)(moving magnetic features, MMFs)之間的關(guān)系還不是很清楚。而這兩者之間可能存在的關(guān)系,對于解釋太陽基本結(jié)構(gòu)的形成機(jī)制是十分重要的。通過對來自NVST的H α與SDO的多波段觀測數(shù)據(jù)對編號為11711的太陽活動區(qū)的分析發(fā)現(xiàn),每一個運動磁結(jié)構(gòu)都是從亮橋北部附近的半影區(qū)域浮現(xiàn)。它們極性與對應(yīng)的黑子極性相反,并且總是有相應(yīng)的暗纖維相連。這些暗條纖維不斷地扭纏與重組,形成了具有三條分支的拱狀暗條系統(tǒng)。這些運動磁結(jié)構(gòu)不斷地與北部周圍的正極磁場對消,產(chǎn)生了各種活動,使得拱狀暗條的北部足點重聯(lián)并最終瓦解。
[Abstract]:The sun constantly generates energy and transmits information through electromagnetic radiation and other means. Based on this limited information, scientists think from the whole, simplify details, and back to the sun's energy mechanism, structure and other physical information. The research on the complex giant system of the sun is not only of great significance to astronomy and physics, but also reflects the feedback in system science everywhere. The whole idea plays an important role in heliophysics. The bright bridge in sunspots, Light Bridges (LBs), is a very interesting structure, although it has been studied in detail for decades, but its formation, evolution, disappearance. There are many problems with the magnetic field structure and its relationship with other solar activities. Moving Magnetic Features (MMFs) is another kind of structure associated with sunspots. It is usually described as emerging from the sunspot penumbra. As a basic magnetic structure on the surface of the sun, the moving magnetic structure plays an important role in the decline of the solar active region. However, there are still many unknown questions about the cause of its formation. All of these sunspot related problems need to be solved urgently. The efforts that have been devoted to phenomena related to sunspot structures, such as moving magnetic structures, are of great significance and are of great help in understanding the mechanisms of solar activity. Arch filament systems (AFS) is generally considered to be the representation of the emerging flux region (EFR) in the chromospheric layer. The relationship between it and moving magnetic features (MMFs) around the sunspot is not very clear. It is very important to explain the formation mechanism of the basic structure of the sun. By analyzing the multi-band observation data of H 偽 and SDO from NVST, we find that the solar active region numbered 11711 is found. Each moving magnetic structure emerges from the penumbra near the northern part of the bridge. Their polarity is opposite to the corresponding sunspot polarity, and they are always connected with the corresponding dark fibers, which are constantly twisting and reorganizing. These moving magnetic structures are constantly counteracted with the positive magnetic field around the north resulting in a variety of activities resulting in the reconnection and eventual disintegration of the northern foot of the arch strip.
