This work will perform a near-infrared precision radial velocity survey of 100 late M-dwarf stars and brown dwarfs in order to search for new Saturn- or Jupiter-mass exoplanets. The PI and his team plan to use an ammonia gas cell with the IRCS spectrograph on the 8-m Subaru Telescope in order to obtain moderate-resolution spectra of exoplanets. They will then use these measurements to constrain models of planet formation. The team plans to make the cell available to US investigators, which will greatly aid in follow-up radial velocity studies for confirmation of exoplanet discoveries. Undergraduate students in be supervised and mentored in research, including observational and data reduction techniques.

这项工作将对100颗晚期m矮星和褐矮星进行近红外精确径向速度测量，以寻找新的土星或木星质量的系外行星。PI和他的团队计划使用氨气电池和8米斯巴鲁望远镜上的IRCS光谱仪，以获得系外行星的中等分辨率光谱。然后，他们将利用这些测量结果来约束行星形成的模型。该团队计划将该细胞提供给美国研究人员，这将极大地帮助后续的径向速度研究，以确认系外行星的发现。本科生将在研究方面受到监督和指导，包括观察和数据简化技术。
