Propagation of solar oscillations through the interplanetary medium

Lanzerotti, Louis J.; Thomson, David J.; Maclennan, Carol G.

Time-series analysis of the fluxes of interplanetary charged particles measured by the Ulysses and Voyager spacecraft reveals many periodic components. From 1 to 140 µHz, the spectral components are consistent with those estimated (but not confirmed) for gravity-mode oscillations of the Sun: from 1,000 to 4,000 µHz, the spectral lines closely matc…
