Fig. 15


Hα (bottom panel) and Hβ (top panel) emission lines of MWC 314 show largest normalised flux maxima at φ ≃ 0.65 (spectrum Nos. 6 and 16), and smallest flux maxima at φ ≃ 0.32 (Nos. 13, 15, and 7). The absolute emission line fluxes determined with the V-brightness curve are however almost invariable, indicating that the extended circumbinary Hα and Hβ emission line formation regions are little influenced by the orbital motion.
