太阳耀斑激发的太阳黑子振荡的初步观测
Initial Observations of Sunspot Oscillations Excited by Solar Flare
摘要:
2006年12月13日,使用太阳光学望远镜(SOT)对一个大的太阳耀斑进行了观测,发现耀斑在太阳黑子色球层中激发了高频振荡。这些振荡是在太阳黑子本影的强磁场区观测到的,可能为探测太阳黑子结构和理解太阳耀斑的物理过程提供一种新的诊断工具。
英文摘要:
Observations of a large solar flare of December 13, 2006, using Solar Optical Telescope (SOT) on Hinode spacecraft revealed high-frequency oscillations excited by the flare in the sunspot chromosphere. These oscillations are observed in the region of strong magnetic field of the sunspot umbra, and may provide a new diagnostic tool for probing the structure of sunspots and understanding physical processes in solar flares.
