We present fast photometric observations of KR Aurigae, a nova-like variable, made during 1984-1988, in the B and U bands. The light curves show large-amplitude pulsations with periods in the range 480-780 s. The period is found to be different even on consecutive nights and, therefore, these pulsations are interpreted as quasi-periodic in nature. The pulsation periods in the bright state are positively correlated with the source intensity, but the low-state periods do not follow this linear trend. We discuss possible explanations of the quasi-periodic oscillations. Pulsations with period in the 1050-1600 s range are also found in the data, which can be attributed to broader features seen in the light curves

Times of maxima of the pulsations in the intermediate polar 3A 0729+103 (BG CMi) are obtained from observations made during 1984-1989. From a quadratic fit to the residuals of the times of maxima the pulsation period is obtained to be 0.010572966 (±8) day and the white is found to be spinning up at a rate of 5.7 (±0.6) × 10 −11 . The spin-up time scale, |P/P|, is 5.0 × 10 5 yr, which is much smaller than the time scale of binary evolution. This implies that accretion plays an important role in the dynamics of this system. The rate of change of the pulsation period of 3A 0729+103 is found to be similar to that measured for five other intermediate polars.
