Hinode/SOT的初始日震观测
Initial Helioseismic Observations by Hinode/SOT
摘要：
报道了日之出太阳光学望远镜日震观测的初步结果。它已被证明，从宽带滤波成像仪的强度振荡数据可以用于各种日震分析。的k Ω功率谱，以及相应的时间-距离交叉关联函数，承诺高分辨率的时间-距离分析低于6毫米的旅行距离，获得G-波段和CAII-H数据。从我们第一次的时间-距离分析中已经观察到了亚表面的超颗粒图案。结果表明，太阳振荡谱扩展到更高的频率和波数，和时间-距离图扩展到更短的旅行距离和时间比以前观察到的，从而揭示了高分辨率日震观测的巨大潜力。
英文摘要：
Results from initial helioseismic observations by Solar Optical Telescope onboard Hinode are reported. It has been demonstrated that intensity oscillation data from Broadband Filter Imager can be used for various helioseismic analyses. The k-omega power spectra, as well as corresponding time-distance cross-correlation function that promises high-resolution time-distance analysis below 6-Mm travelling distance, were obtained for G-band and CaII-H data. Subsurface supergranular patterns have been observed from our first time-distance analysis. The results show that the solar oscillation spectrum is extended to much higher frequencies and wavenumbers, and the time-distance diagram is extended to much shorter travel distances and times than they were observed before, thus revealing great potential for high-resolution helioseismic observations from Hinode.
