论文摘要
诊断太阳上磁通量的空间时空模式对于理解太阳磁和活性的起源至关重要。在这里，我们报告了一种新形式的通量外观，磁性爆发，使用在大熊太阳能天文台的1.6 m Goode太阳能望远镜（GST）中的空间分辨率极高的0.16 ARCSEC的观测值。磁暴发是指单极磁通量的早期生长及其后来的爆炸成碎片，与等离子体上流和爆炸颗粒有关。每个单独的片段的通量为10 $^{16} $ -10 $^{17} $ mx，速度为0.5-2.2 km/s。磁性暴发发生在毛孔护城河的公升区域。在这项研究中，我们在6小时观察结果中确定了六次磁性爆发事件，大约40美元$ \ times $ 40 arcsec $^{2} $视野。新发现的磁性爆发可能是长期以来的对流爆炸的第一个证据。
Diagnosing the spatial-temporal pattern of magnetic flux on the Sun is vital for understanding the origin of solar magnetism and activity. Here, we report a new form of flux appearance, magnetic outbreak, using observations with an extremely high spatial resolution of 0.16 arcsec from the 1.6-m Goode Solar Telescope (GST) at the Big Bear Solar Observatory. Magnetic outbreak refers to an early growth of unipolar magnetic flux and its later explosion into fragments, in association with plasma upflow and exploding granulations; each individual fragment has flux of 10$^{16}$-10$^{17}$ Mx, moving apart with velocity of 0.5-2.2 km/s. The magnetic outbreak takes place in the hecto-Gauss region of pore moats. In this study, we identify six events of magnetic outbreak during 6-hour observations over an approximate 40$\times$40 arcsec$^{2}$ field of view. The newly discovered magnetic outbreak might be the first evidence of the long-anticipated convective blowup.
