项目摘要

With the new datasets from IRD/Subaru, we confirmed our previously detected OH and atomic species on the day side of WASP-33b. We followed it up by resolving the 2 strongest vibrational bands of OH individually as a first step to searching for NLTE signature. From the same datasets, we found evidence of new detection of other atomic species and a non-homogeneous atmosphere indicated by a much weaker/non-detection of OH before than after the secondary eclipse. We constructed a framework to fit the evolution of the line contrast of the planetary spectrum with time using JAX+GPU and confirmed that the line contrast is much higher after the eclipse.We found no chemical species signature in the atmosphere of a warm super earth, GJ 486b, and excluding H2/He-dominated or a clear 100% water-vapour atmosphere by using IRD, SPIRou and IGRINS data. This potentially suggests that rocky planets around M-dwarf stars might have lost their atmospheres. Using ESPRESSO and UVES at the VLT, we found consistent relative abundance constraints in the WASP-121b transmission spectra across multiple observations demonstrating our robust technique that can be applied to future analyses.
通过IRD/Subaru的新数据集,我们证实了我们之前在WASP-33 b的白天检测到的OH和原子种类。我们随后通过单独解析OH的2个最强振动带作为搜索NLTE签名的第一步。从相同的数据集,我们发现了其他原子物种和非均匀大气的新检测的证据,这表明在二次日食之前比二次日食之后更弱/未检测到OH。利用IRD、SPIRou和IGRINS数据,在温暖的超级地球GJ 486 b大气中没有发现化学物质的特征,排除了H2/He为主或100%水汽的大气。这可能表明,M矮星周围的岩石行星可能已经失去了大气层。在VLT使用ESTERO和UVES,我们在WASP-121 b透射光谱中发现了一致的相对丰度限制,这表明我们的强大技术可以应用于未来的分析。
