摘要

“鸸鹋”是一个紧凑的宽视场光度计，将于2021年开始在国际空间站(ISS)外部执行为期6个月的任务。Emu将在1.4 μm“水带”进行巡天，作为估计低温恒星大气中氧丰度的一种方法，其亮度低至mAB≈13 (h波段)。

Emu: a near-infrared wide-field photometer for space

‘Emu’ is a compact wide-field photometer destined for a 6-month mission on the exterior of the International Space Station (ISS), commencing in 2021. Emu will undertake a sky survey in the 1.4 μm ‘water band’, as a method of estimating oxygen abundance in the atmospheres of cool stars down to a magnitude of mAB≈13 (H-band).
