在下一代红外天基巡天中使用依赖于水的颜色项探测自由浮动行星
Detecting free-floating planets using water-depend colour terms in the next generation of infrared space-based surveys
摘要：
未来十年将进行两次大规模的天基近红外勘测：Euclid和WFIRST。本文表明，这些调查和地面测光系统的过滤器之间的细微差别将产生地面空间的颜色项，这是依赖于水的吸收光谱的天文物体。这个颜色项可以用来识别恒星形成区域中自由漂浮的行星，模仿一种成功的地面技术，使用对水吸收敏感的过滤器。本文表明，该色项是红化背景星与超冷矮星的有效判别。这只是一个科学的理由，银河平面调查的情况下，延长欧几里德任务超出其原来的时间表。
英文摘要：
The next decade will see two large-scale space-based near-infrared surveys, Euclid and WFIRST. This paper shows that the subtle differences between the filters proposed for these surveys and those from ground-based photometric systems will produce a ground-space colour term that is dependent on water absorption in the spectra of astronomical objects. This colour term can be used to identify free-floating planets in star forming regions, mimicking a successful ground-based technique that uses a filter sensitive to water absorption. This paper shows that this colour term is an effective discriminant between reddened background stars and ultracool dwarfs. This represents just one science justification for a Galactic Plane survey in the event of an extension to the Euclid mission beyond its original timeframe.
