摘要
基于超高指向精度和超高稳定度的新型卫星平台,中国首颗太阳探测科学与技术试验卫星“羲和号”搭载的科学载荷Hα成像光谱仪在国际上首次实现了太阳Hα波段光谱成像的空间观测,像元光谱分辨率0.024Å,全日面扫描时间46 s,空间分辨率1.2"。论述了利用“羲和号”的高质量科学数据,国内外学者在太阳活动的低层大气动力学过程,太阳暗条的形成、演化和爆发,以及太阳和恒星爆发的比较研究中取得的系列原创科学成果。
The Chinese HαSolar Explorer(CHASE),dubbed"Xihe"–Goddess of the Sun,is China's first solar space mission for both scientific and technological experiments.Since its launch on October 14,2021,it has been operating well in orbit with excellent scientific data quality.Based on a new type of satellite platform with ultra-high pointing accuracy and ultra-high stability,the HαImaging Spectrograph(HIS)onboard the CHASE mission has,for the first time in the world,achieved space-based spectroscopic observations in the solar Hαwaveband.The pixel spectral resolution reaches~0.024Å,the full-disk scanning time is~46 seconds,and the spatial resolution is~1.2 arcseconds.Using the high-quality data from CHASE,researchers have achieved a series of original scientific results in the dynamic processes of solar activities in the lower atmosphere,the formation,evolution,and eruption of solar filaments,as well as comparative studies of solar and stellar eruptions.
