利用SAFARI进行系外行星研究：用于SPICA的远红外成像光谱仪
Exoplanet research with SAFARI: A far-IR imaging spectrometer for SPICA
摘要：
远红外光谱窗口可以进行广泛的光谱和光度诊断，从而将原行星盘和系外行星研究开放到完全被地球大气层阻挡的波长。这些包括一些关键的原子（例如，氧）和分子（例如，水）冷却管线、尘埃热辐射、水冰特征以及许多其他关键化学示踪剂。这些特征中的大多数无法从地面望远镜观察到，但在许多关键领域发挥了关键的诊断作用，包括行星形成的早期阶段和潜在的系外行星。日本主导的红外空间望远镜SPICA，其3.5米冷却镜将是赫歇尔之后的下一个灵敏度。SPICA最近被选中进入欧空局2015-2025年宇宙愿景进程的下一阶段。本文总结了SAFARI的设计理念：一个覆盖~30- 210 um波段的成像远红外光谱仪，是SPICA的一套仪器之一;它还强调了一些科学问题，它将有可能在系外行星和行星形成领域解决。
英文摘要：
The far-IR spectral window plays host to a wide range of both spectroscopic and photometric diagnostics with which to open the protoplanetary disks and exoplanet research to wavelengths completely blocked by the Earth's atmosphere. These include some of the key atomic (e.g., oxygen) and molecular (e.g., water) cooling lines, the dust thermal emission, the water ice features as well as many other key chemical tracers. Most of these features can not be observed from ground-based telescopes but play a critical diagnostic in a number of key areas including the early stages of planet formation and potentially exoplanets. The proposed Japanese-led IR space telescope SPICA, with its 3.5m cooled mirror will be the next step in sensitivity after Herschel. SPICA has been recently selected to go to the next stage of the ESA's Cosmic Vision 2015-2025 process. This contribution summarizes the design concept behind SAFARI: an imaging far-IR spectrometer covering the ~30-210um waveband that is one of a suite of instruments for SPICA; it also highlights some of the science questions that it will be possible to address in the field of exoplanets and planet formation.
