项目摘要

We developed an "ammonia gas cell" as a high quality wavelength calibrator and installed it into the Infrared Camera and Spectrograph of Subaru Telescope. With this device, we started a high resolution infrared spectroscopic search for "Earth like" extrasolar planets with <10 earth masses. We achieved a velocity precision of 23. 6 m/s, which is the highest among the world spectrographs with a spectral resolution (λ・△λ) of around 20, 000. In addition, we successfully fabricated a new dispersion optics with an Si immersion grating for future very high-resolution infrared spectroscopy.

我们开发了一种“氨气电池”作为高质量的波长校准器，并将其安装到斯巴鲁望远镜的红外相机和摄谱仪中，通过该设备，我们开始了对小于10个地球的“类地”太阳系外行星的高分辨率红外光谱搜索。我们实现了 23. 6 m/s 的速度精度，这是光谱分辨率（λ・△λ）约为世界上最高的光谱仪。 20, 000。此外，我们成功地制造了一种带有硅浸没光栅的新型色散光学器件，用于未来的超高分辨率红外光谱。
