- Аннотация: Positive superhumps are hump-shaped modulations in light curves of some Cataclysmic Variables (CVs) that have a period that is slightly longer than the orbital period. In CV SU UMa-like systems, the shape of the positive superhump is known to change throughout the superoutburst, which thus slightly changes the published, observed, positive superhump period. In this presentation, we analyze numerical simulations of prograde precession in accretion disks of CV SU UMa-like systems near superoutburst maximum. We compare the simulated positive superhump shapes with the shapes obtained from observations, using AW Sge as our model. Similarly, we compare associated Fourier Transforms with associated periodograms. We conclude with our analysis of the likely sources that generate the shape of the positive superhump in CV SU UMa-like systems near superoutburst maximum.
