| contents | 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! |
