[en] Spectral modelling and especially for massive stars is not a straightforward problem and over the past decades many advances have been made in this field. We now have very efficient model atmosphere codes such as CMFGEN and TLUSTY for example. However, these codes are based on the assumption that the star is single and spherical which is no longer valid for the components of a binary system. On the other hand, observational studies indicate that binarity has an impact on the spectra and binary interactions impact the analyses of the spectra. This is why we have developed a very first model called CoMBiSpeC (code of massive binary spectral computation). We present here some examples of the impact of the binarity on the shape of the stars and the resulting effects on their spectra.
