Chemical Characterisation of Sub-stellar Atmospheres

我的项目包括分析亚恒星体的光谱，以确定它们的成分，这可能使我们能够限制它们的形成和演化。为了进行分析，我使用大气检索方法，通过拟合正演模型来获得分子丰度和压力-温度分布。目前，我正在分析褐矮星光谱，目的是限制它们的组成和对它们的形成施加限制。这也涉及到使检索方法适应棕矮星大气。在未来，我将把这种方法应用到其他对象中，并继续开发检索方法，以适应可用数据质量的提高。

My project involves analysing the spectra of sub-stellar bodies to determine their compositions, which may allow us to constrain their formation and evolution. To do this analysis, I am using atmospheric retrieval methods which derive molecular abundances and pressure-temperature profiles by fitting forward models to an observed spectrum. Currently, I am analysing brown dwarf spectra with the aim of constraining their compositions and placing constraints on their formation. This also involves adapting the retrieval method to brown dwarf atmospheres.In the future, I will apply this method to other objects and continue to develop the retrieval method in order to adapt to the increasing quality of the available data.
