tau: A 1D radiative transfer code for transmission spectroscopy of extrasolar planet atmospheres

Abstract The tau code is a 1 D line-by-line radiative transfer code, which is generally applicable for modelling transmission spectra of close-in extrasolar planets. The inputs are the assumed pressure–temperature profile of the planetary atmosphere, the continuum absorption coefficients and the absorption cross-sections for the trace molecular absorbers present in the model, as well as the fundamental system parameters taken from the published literature. The program then calculates the optical path ...

摘要 tau代码是一款一维逐行辐射传输代码（radiative transfer code），可广泛用于近距离系外行星的透射光谱（transmission spectra）建模。其输入参数包含预设的行星大气温压剖面（pressure–temperature profile）、连续吸收系数（continuum absorption coefficients）、模型中涉及的痕量分子吸收体的吸收截面（absorption cross-sections），以及从已发表文献中提取的基础系统参数。随后该程序将计算光程（optical path）……
