解开系外行星生物印记之谜：英国主导的红外光谱仪用于可居住世界观测冠形光谱仪
The Key to Unlocking Exoplanet Biosignatures: a UK-led IR Spectrograph for the Habitable Worlds Observatory Coronagraph
AI总结：
英国主导开发近红外光谱仪，用于可居住世界观测项目，旨在通过检测多个分子大气特征来寻找潜在宜居系外行星上的生命迹象。
摘要：
在附近恒星的宜居带中发现 rocky exoplanets 上的生命将是一个范式转变的进展，也是当今最伟大的科学挑战之一。没有单一的光谱特征是某个系外行星上生命的无歧义标志。目前的最先进技术涉及检测多个分子大气特征，这些特征在平衡状态下不应同时存在，例如同时检测 O₂ 和 CH₄。需要覆盖宽波长范围（0.3-1.7 μm）的光谱，以覆盖每个感兴趣分子的多个光谱特征，并对检测到的分子特征套件进行上下文化。虽然美国将领导可居住世界观测（HWO）冠形光谱仪的光学臂，但英国主导的近红外积分场光谱仪（IFS）将用于红外臂，确保英国在 HWO 的旗舰科学目标上的领导地位——即在可能宜居的系外行星上寻找生命的迹象。
英文摘要：
The detection of life on rocky exoplanets in the habitable zones of nearby stars would be a paradigm-shifting advance, and it is one of the greatest scientific challenges of our time. There is no single spectral feature that is an unambiguous sign of life on a given exoplanet. Instead, the current state-of-the-art approach involves detecting multiple molecular atmospheric features that should not exist together in equilibrium, e.g. simultaneous detection of O$_2$ and CH$_4$. Spectra across a wide wavelength (0.3-1.7 $μ$m) range are necessary to cover multiple spectral features per molecule of interest and to contextualise the suite of molecular features detected. While the US will lead the optical arm of the Habitable Worlds Observatory (HWO) coronagraph, a UK-led contribution of a near-infrared Integral Field Spectrograph (IFS) for the infrared arm will ensure UK leadership in the flagship scientific goal of HWO - to search for signatures of life on potentially habitable exoplanets.
