Abstract: In this study, we present photometric and spectroscopic variations of the extremely small mass ratio (q ≃ 0.1) late-type contact binary system V1191 Cyg. The parameters for the hot and cooler companions have been determined as Mh = 0.13 (1) M⊙, Mc = 1.29 (8) M ⊙, Rh = 0.52 (15) R⊙, Rc = 1.31 (18) R⊙, Lh = 0.46 (25) L⊙, Lc = 2.71 (80) L⊙, the separation of the components is a = 2.20 (8) R⊙ and the distance of the system is estimated as 278 (31) pc. Analyses of the times of minima indicates a period increase of dPdt=1.3(1)×10-6days/yr that reveals a very high mass transfer rate of dMdt=2.0(4)×10-7M⊙/yr from the less massive component to the more massive one. New observations show that the depths of the minima of the light curve have been interchanged. © 2011 Elsevier B.V. All rights reserved.
