测量系外行星大气中碳和氧的丰度被认为是解开系外行星系统形成和演化的关键途径。获取系外行星的化学清单需要高精度的观测，这通常是从低分辨率天基和高分辨率地基设施的单个分子探测中推断出来的。在这里，我们报告的中分辨率（R 600）的3和5 μm之间的系外行星大气的透射光谱，涵盖了土星质量的系外行星WASP-39 b（参考）的几个吸收特征，获得了近红外光谱仪（NIRSpec）G395 H光栅的JWST。我们的观测实现了1.46倍的光子精度，提供了一个平均过境深度的不确定性为221 ppm的光谱箱，并提出最小的影响，从系统的影响。我们检测到来自CO2（28.5σ）和H2O（21.5σ）的显著吸收，并确定SO2为4.1 μm（4.8σ）处的吸收源。最适合的大气模型范围在太阳金属丰度的3到10倍之间，具有太阳下到太阳的C/O比率。这些结果，包括SO2的探测，强调了表征系外行星大气化学的重要性，并展示了NIRSpec G395 H作为在这一关键波长范围内进行时间序列观测的优秀模式。系外行星WASP-39 b的中等分辨率透射光谱，使用JWST上的近红外光谱仪G395 H光栅进行观测，显示出对CO2和H2O的显著吸收以及对SO2的检测。
Measuring the abundances of carbon and oxygen in exoplanet atmospheres is considered a crucial avenue for unlocking the formation and evolution of exoplanetary systems. Access to the chemical inventory of an exoplanet requires high-precision observations, often inferred from individual molecular detections with low-resolution space-based and high-resolution ground-based facilities. Here we report the medium-resolution (R ≈ 600) transmission spectrum of an exoplanet atmosphere between 3 and 5 μm covering several absorption features for the Saturn-mass exoplanet WASP-39b (ref. ), obtained with the Near Infrared Spectrograph (NIRSpec) G395H grating of JWST. Our observations achieve 1.46 times photon precision, providing an average transit depth uncertainty of 221 ppm per spectroscopic bin, and present minimal impacts from systematic effects. We detect significant absorption from CO2 (28.5σ) and H2O (21.5σ), and identify SO2 as the source of absorption at 4.1 μm (4.8σ). Best-fit atmospheric models range between 3 and 10 times solar metallicity, with sub-solar to solar C/O ratios. These results, including the detection of SO2, underscore the importance of characterizing the chemistry in exoplanet atmospheres and showcase NIRSpec G395H as an excellent mode for time-series observations over this critical wavelength range. The medium-resolution transmission spectrum of the exoplanet WASP-39b, described using observations from the Near Infrared Spectrograph G395H grating aboard JWST, shows significant absorption from CO2 and H2O and detection of SO2.
