Reproduction package for "Probing reflection from aerosols with the near-infrared dayside spectrum of WASP-80b"

This is a basic reproduction package for the paper "Probing reflection from aerosols with the near-infrared dayside spectrum of WASP-80b" by [Jacobs, B.; Désert, J. -M.; Gao P. et al. (2023)](https://doi.org/10.3847/2041-8213/acfee9). Abstract: The presence of aerosols is intimately linked to the global energy budget and the composition of a planet's atmospheres. Their ability to reflect incoming light prevents energy from being deposited into the atmosphere, and they shape spectra of exoplanets. We observed five near-infrared secondary eclipses of WASP-80b with the Wide Field Camera 3 (WFC3) aboard the Hubble Space Telescope to provide constraints on the presence and properties of atmospheric aerosols. We detect a broadband eclipse depth of 34\pm10 ppm for WASP-80b. We detect a higher planetary flux than expected from thermal emission alone at 1.6 sigma, which hints toward the presence of reflecting aerosols on this planet's dayside, indicating a geometric albedo of A_g<0.33 at 3 sigma. We paired the WFC3 data with Spitzer data and explored multiple atmospheric models with and without aerosols to interpret this spectrum. Albeit consistent with a clear dayside atmosphere, we found a slight preference for near-solar metallicities and for dayside clouds over hazes. We exclude soot haze formation rates higher than 10^{-10.7} g cm^{-2} s^{-1} and tholin formation rates higher than 10^{-12.0} g cm^{-2} s^{-1} at 3 sigma. We applied the same atmospheric models to a previously published WFC3/Spitzer transmission spectrum for this planet and found weak haze formation. A single soot haze formation rate best fits both the dayside and the transmission spectra simultaneously. However, we emphasize that no models provide satisfactory fits in terms of the chi-square of both spectra simultaneously, indicating longitudinal dissimilarity in the atmosphere's aerosol composition.本数据集为论文《利用WASP-80b的近红外昼面光谱探测气溶胶反射》（英文原标题："Probing reflection from aerosols with the near-infrared dayside spectrum of WASP-80b"）的基础复现包，作者为Jacobs, B.; Désert, J.-M.; Gao P. 等(2023)，DOI链接：https://doi.org/10.3847/2041-8213/acfee9。 摘要：气溶胶的存在与行星大气的全球能量收支及组分紧密相关。其反射入射光线的能力可阻止能量沉积至大气中，并塑造系外行星的光谱特征。我们借助哈勃空间望远镜（Hubble Space Telescope）搭载的宽视场相机3（Wide Field Camera 3, WFC3），对WASP-80b开展了5次近红外次级食观测，以期为大气气溶胶的存在与属性提供约束。 我们测得WASP-80b的宽带食深为34±10 ppm。在1.6σ置信水平下，我们探测到的行星辐射通量高于纯热辐射的预期值，这暗示该行星昼面存在反射性气溶胶，在3σ置信水平下可推得其几何反照率A_g<0.33。 我们将WFC3观测数据与斯皮策（Spitzer）数据相结合，构建并测试了包含与不包含气溶胶的多款大气模型以解析该光谱。 尽管结果与无云昼面大气的假设一致，但我们发现模型更偏好近太阳金属丰度，且昼面云相较于霾更适配数据。在3σ置信水平下，我们排除了烟炱霾生成率高于10^{-10.7} g·cm^{-2}·s^{-1}以及托林（tholin）生成率高于10^{-12.0} g·cm^{-2}·s^{-1}的情景。 我们将同款大气模型应用于该行星此前已发表的WFC3/斯皮策透射光谱数据集，发现仅存在微弱的霾生成信号。 单一烟炱霾生成率可同时最优拟合昼面光谱与透射光谱。但我们需强调，尚无模型能同时在两款光谱的卡方检验中取得令人满意的拟合效果，这表明该行星大气的气溶胶组分存在经度差异。
