Abstract

Here, we provide supplementary material for the article "Ultraviolet spectroscopy reveals a hot and luminous companion to the Be star + black hole candidate MWC 656". This includes the newly calculated PoWR model spectra for the Be star and the stripped companion. We provide normalised spectra for both stars in the UV and the optical regime, as well as the combined model SED of the system. (The UV spectrum of the Be star contains narrow absorption lines from simulated ISM.)
