标题： Physics Of Eclipsing Binaries. IX. Spectroscopic module

摘要： 光谱观测限定了恒星大气的基本特性，特别是有效温度、重力加速度或金属丰度。 在本工作中，我们描述了Phoebe中的光谱模块，该模块允许对光谱进行建模，无论是归一化的还是绝对单位的（${\rm W}\,{\rm m}^{-2}\,{\rm m}^{-1}$）。 该模块基于从文献中获取的广泛合成光谱网格，这些网格在表面进行插值和积分。 作为近似，我们假设边缘暗化由解析定律给出，而其他效应（例如，掩食）则自洽地处理。 我们的方法适用于单星、双星或多星系统，并可进一步扩展到包含脉动成分的系统。 此草案指的是Phoebe的一个开发版本，可在https://github.com/miroslavbroz/phoebe2/tree/spectroscopy2 获取。 它尚未包含在官方的Phoebe仓库中！ 显示英文摘要

摘要： Spectroscopic observations constrain the fundamental properties of stellar atmospheres, in particular, the effective temperature, the gravitational acceleration, or the metallicity. In this work, we describe the spectroscopic module for Phoebe, which allows for modelling of spectra, either normalized, or in absolute units (${\rm W}\,{\rm m}^{-2}\,{\rm m}^{-1}$). The module is based on extensive grids of synthetic spectra, taken from literature, which are interpolated and integrated over the surface. As an approximation, we assume that limb darkening is given by an analytical law, while other effects (e.g., eclipses) are treated self-consistently. Our approach is suitable for single stars, binaries, or multiples, and can be further extended to systems with pulsating components. This draft refers to a development version of Phoebe, available at https://github.com/miroslavbroz/phoebe2/tree/spectroscopy2 . It is not yet included in the official Phoebe repository!
