Superfast Exoplanets and 9600 s

Abstract

Motion of a substantial part of the superfast exoplanets is found to be in the close resonance with the well-known “solar” timescale $P_{0} \approx 0.11$ days and/or the timescale 2$P_0$/$\pi \approx 0.07$ days (at 99.9% confidence for exoplanet periods $P < 2$ days). There is also a noticeable lack of the exoplanetary “unstable” orbits with $P \approx 3 \pi$$P_0$$\,\approx 1.05$ days, which copies the famous “period gap” of the cataclysmic variables at $P \approx 0.11$ days; strangely enough, the ratio of the central periods of these two gaps is equal to $\pi ^2$. The exoplanet phenomenon is supposed to be caused by a coherent, with the $P_0$ timescale, oscillation of gravity, operating within the extra-solar planetary systems.
