土星质量的系外行星WASP-39b一直是利用透射谱确定其大气性质的广泛努力的对象。然而，由于数据质量有限导致合成和云属性之间的模型退化，这些努力一直受到阻碍。本文给出了在JWST上利用近红外成像仪和无狭缝光谱仪(NIRISS)的单目标无狭缝光谱(SOSS)模式获得的WASP-39b的透射谱。这一光谱的波长跨度为0.6-2.8 μm，并显示了几个水吸收带、钾共振双峰和云的特征。NIRISS/SOSS的精度和宽广的波长覆盖范围使我们能够打破WASP-39b云特性和大气组成之间的模型简并，有利于重元素增强(金属丰度)约为太阳值的10-30倍，亚太阳碳氧比(C/O)和太阳超太阳钾氧比(K/O)。这些观测也可以用波长相关的非灰色云团来解释，这些云团覆盖着行星的终结点，而且覆盖不均匀。系外行星WASP-39b的透射谱是利用JWST上的近红外成像仪和无狭缝光谱仪的单目标无狭缝光谱模式的观测获得的。
The Saturn-mass exoplanet WASP-39b has been the subject of extensive efforts to determine its atmospheric properties using transmission spectroscopy. However, these efforts have been hampered by modelling degeneracies between composition and cloud properties that are caused by limited data quality. Here we present the transmission spectrum of WASP-39b obtained using the Single-Object Slitless Spectroscopy (SOSS) mode of the Near Infrared Imager and Slitless Spectrograph (NIRISS) instrument on the JWST. This spectrum spans 0.6–2.8 μm in wavelength and shows several water-absorption bands, the potassium resonance doublet and signatures of clouds. The precision and broad wavelength coverage of NIRISS/SOSS allows us to break model degeneracies between cloud properties and the atmospheric composition of WASP-39b, favouring a heavy-element enhancement (‘metallicity’) of about 10–30 times the solar value, a sub-solar carbon-to-oxygen (C/O) ratio and a solar-to-super-solar potassium-to-oxygen (K/O) ratio. The observations are also best explained by wavelength-dependent, non-grey clouds with inhomogeneous coverageof the planet’s terminator. The transmission spectrum of the exoplanet WASP-39b is obtained using observations from the Single-Object Slitless Spectroscopy mode of the Near Infrared Imager and Slitless Spectrograph instrument aboard the JWST.
