Abstract

Differential measurements (1974–1988) of the solar velocity and photospheric brightness show the presence of long-term pulsation of the Sun with a period of Po=160.0101(±1) min. Its nature is poorly known since it seems hardly possible to explain the periodicity in terms of solar g-modes. But the most fascinating appears to be the recent discovery of the same 160-min periodicity in the light-flux variations of several AGN (active galactic nuclei). This finding strongly supports the hypothesis advanced much earlier about cosmological origin of the oscillation.
