Ellipsoidal Binaries: Rotation, Ellipsoidal Binaries: Periods

Scientific paper

The origin of pulsation of the Sun with period P0 ≍ 160 min is as yet unknown. Statistical treatment of data on the rotation of 43 ellipsoidal binary systems with Porb < 7 days showed that the most resonant frequency of these stars equals 104.6±0.6 μHz. This agrees well with the frequency ν0 = P0-1 = 104.1601±0.0001 μHz found earlier in global solar oscillations, and also in: (1) pulsation frequencies of δ Sct stars and (2) in rapid variability of AGNs. These findings thus strongly favour a cosmological interpretation of the "ubiquitous" 160-min periodicity.
