Rapid oscillations in cataclysmic variables. II. The 63 second oscillation of V533 Herculis.
Abstract
The discovery of rapid coherent oscillations in the light curve of the remnant of Nova Herculis 1963 (=V533 Her) is reported. The oscillation is continuously present and strictly periodic, with a period of 63.63309 + or - 0.00004 s, and a mean amplitude of 1%. The brightness of the star in 1978 (B = 15.7 mag) suggests that it experienced a 'preoutburst brightening' by 2 mag over about 40 years. The properties of the oscillation are very similar to those of the 71-s oscillation of DQ Her, but the outburst properties of these two classical novae were very different.
