在特内里费岛观测太阳的GOLF-NG仪器原型的首次性能
First performances of the GOLF-NG instrumental prototype observing the Sun in Tenerife
摘要：
GOLF-NG（新一代低频全球振荡）的主要挑战是探测低频太阳重力和声学模式，以及测量高频色球模式的可能性。2008年6月8日，在特内里费岛天文台（Observatorio del Teide）首次使用多通道共振GOLF-NG原型光谱仪进行了太阳光观测。该仪器同时在D1钠谱线的八个不同高度进行综合（太阳作为恒星）多普勒速度测量，这些高度对应于太阳大气的光球层和色球层。为了研究其性能，验证所设想的策略，并评估必要的改进，该原型在整个2008年夏天每天都在天文台运行。我们在这里介绍的第一GOLF-NG观测结果，清楚地显示了在太阳大气中的不同高度的5分钟振荡信号的特征。我们将这些信号与GOLF/SOHO和Mark-I仪器（BiSON网络的一个节点，在同一站点运行）的同时观测结果进行比较。
英文摘要：
The primary challenge of GOLF-NG (Global Oscillations at Low Frequency New Generation) is the detection of the low-frequency solar gravity and acoustic modes, as well as the possibility to measure the high-frequency chromospheric modes. On June 8th 2008, the first sunlight observations with the multichannel resonant GOLF-NG prototype spectrometer were obtained at the Observatorio del Teide (Tenerife). The instrument performs integrated (Sun-as-a-star), Doppler velocity measurements, simultaneously at eight different heights in the D1 sodium line profile, corresponding to photospheric and chromospheric layers of the solar atmosphere. In order to study its performances, to validate the conceived strategy, and to estimate the necessary improvements, this prototype has been running on a daily basis over the whole summer of 2008 at the Observatorio del Teide. We present here the results of the first GOLF-NG observations, clearly showing the characteristics of the 5-minute oscillatory signal at different heights in the solar atmosphere. We compare these signals with simultaneous observations from GOLF/SOHO and from the Mark-I instrument -- a node of the BiSON network, operating at the same site.
