论文摘要
天王星的Herschel/Spire观察结果用于在41.74 cm $^{ - 1} $下搜索平流层氯化物（HCl）发射。未检测到HCl，而是确定了3美元的上限； $ <$ <$ 6.2 ppb（$ <$ <$ 2.0 $ \ times $ 10 $^{14} $ molecules/cm $^{2} $用于0.1 MBAR步骤配置文件，$ <$ <$ <$ <$ <$ <$ <$ <$ <$ <$ 1.2 $ \ times $ 10 $ 10 $^{14} $ MORECULES/cm $ $^} HCL有望具有外部来源，这些上限与其他大量外部物种（CO，H $ _2 $ O，CO $ _2 $）和太阳能源来源一致。
Herschel/SPIRE observations of Uranus are used to search for stratospheric hydrogen chloride (HCl) emission at 41.74 cm$^{-1}$. HCl was not detected and instead 3$σ$ upper limits were determined; $<$6.2 ppb ($<$2.0$\times$10$^{14}$ molecules/cm$^{2}$) for a 0.1 mbar step profile and $<$0.40 ppb ($<$1.2$\times$10$^{14}$ molecules/cm$^{2}$) for a 1 mbar step profile. HCl is expected to have an external source and these upper limits are consistent with abundances of other external species (CO, H$_2$O, CO$_2$) and a solar composition source.
