The physical cause of optical spin-period oscillations is usually attributed to the changing viewing aspect of the accretion curtain as it converges near the white dwarf.
The article, which contained " extensive manipulation of differential equations and an ingenious use of exponentially weighted averages ", analyzed seven stability that precludes the inflation from being self-generating, or displaying period-to-period oscillations ."
Over long durations these follow a linear trend, in combination with shorter period oscillations occurring over a few days . These oscillations are unlikely to be the result of rotational module as that would imply a high rotation rate, which would display itself through strong X-ray emissions.
