A pulsar inside the Sun?

Abstract

The Crimean observation of solar oscillations in 1974–1982 showed that the basic period of pulsation of the Sun hidden in its deep interior was equal to P 0=160.0101±0.0001min. More recently, the period was changed to the new value P 1=159.9662±0.0006min, which almost coincided with the annual sidelobe of the former period P 0. The amplitude of the P1 oscillation has increased considerably over 1994–1995. We substantiate the hypothesis that a) the change in the period was caused by the interaction of the P0 oscillation with the rapid rotation of the solar core and that b) the latter has the form of a compact, highly magnetized object like a neutron star rotating with sidereal period P1.
