As we all know, mature sunspots are generally made up of the center’s shadow and the slightly brighter halo half-shadow on the periphery. The appearance of the half shadow of the black is also the standard to distinguish between ordinary black people and small pores. Reporters recently learned from the Yunnan Observatory of the Chinese Academy of Sciences, the Fuxian Lake sun observation and research base in the formation and disappearance of sunspot half shadow research has made new progress. The findings were published in the international journal Astrophysics Journal.
Sunspots are strong magnetic field areas on the sun’s surface, and when there are many sunspots on the sun’s surface, other solar activity is more frequent. Sunspot is the best object to study the balance of magnetic hydrostatic senosis, and it is important to study the relationship between sunspots and other solar activity phenomena by studying the evolution of sunspots.
Dr. Li Qiaoling of the Yunnan Observatory of the Chinese Academy of Sciences, Researcher Yan Xiaoli and others made an in-depth study of the evolution of sunspots in the solar activity zone 12673 using the observation data of the 1 m New Vacuum Telescope (NVST) and the American Solar Dynamics Satellite (SDO). Through the analysis of the change of the blackman’s magnetic field in the process of hent semishadow evolution, it is found that with the increase of the area of the hensemium half shadow, the horizontal field strength of the hensemium half-shadow magnetic field increases and the vertical field intensity decreases, while the horizontal field strength of the half-shadow edifice magnetic field decreases and the vertical field intensity decreases. The newly emerging magnetic flow tube is suppressed by the existing magnetic field, converges to form the half shadow of the sunspot, and under the action of the new aerosol flow, the shadow of the sunspot changes from horizontal to vertical, causing the half shadow of the suntos to disappear.
They also analyzed the evolution of the blackman velocity field during the evolution of the blacks, and found that as the half-shadow of the blackspot formed, the flow of material around the black spot gradually appeared. During the half-shadow decline of the hen, the flow of material near the side of the new degaussion flow area gradually smaller and disappeared. It was also found that the magnetic field environment around the black spot had an effect on the life of the black man , which was short-lived near the area where the flare struck.
