HD 207739 = V1914 Cyg, a tidally distorted F8 supergiant plus an obscured hot non-degenerate star, is presently in a state of episodic mass dumping onto an accretion shell around the hot component. Unrelated to the 141 day orbital cycle, the obscuration has a 50 day periodicity during which most of the UV flux diminishes rapidly, then gradually brightens. The more evolved yet less massive F supergiant is thus presumably shedding mass due to its pulsation.
