2008年1月3日,利用英国红外望远镜上的CGS4带梯级光栅,获得了8P/Tuttle彗星在3449.0 ~ 3462.2 cm−1频率范围内的高分辨率光谱。除了观测到H2O的太阳泵浦荧光线外,较长的积分时间(152分钟)使得8个较弱的H2O特征被分配,其中大多数以前没有在彗星光谱中被识别出来。这些转变来自于更高的能量状态,与Tempel 1号彗星在深度撞击后的光谱中记录的所谓SH线的特征相似。我们已经确定了这些彗星线的某些共同特征,这些特征除了有助于定义这类新的彗星线外,还为它们的产生提供了一些物理过程的线索。最后,我们得到了水的旋转温度和产水速率为(1.4±0.3)× 1028个分子s−1。
High-resolution spectra of comet 8P/Tuttle were obtained in the frequency range 3449.0–3462.2 cm− 1 on 2008 January 3 ut using CGS4 with echelle grating on United Kingdom Infrared Telescope. In addition to observing solar pumped fluorescent lines of H2O, the long integration time (152 min on target) enabled eight weaker H2O features to be assigned, most of which had not previously been identified in cometary spectra. These transitions, which are from higher energy upper states, are similar in character to the so-called SH lines recorded in the post Deep Impact spectrum of comet Tempel 1. We have identified certain characteristics that these lines have in common, and which in addition to helping to define this new class of cometary line give some clues to the physical processes involved in their production. Finally, we derive an H2O rotational temperature of and a water production rate of (1.4±0.3)× 1028 molecules s− 1.
