Latitudinal dependence of the radial IMF component - interplanetary imprint.
Phillips, J.; Smith, E. J.; Goldstein, B. E. +2 more
Ulysses measurements have confirmed that there is no significant gradient with respect to heliomagnetic latitude in the radial component, B_r_, of the interplanetary magnetic field. There are two processes responsible for this observation. In the corona, the plasma β is <<1, except directly above streamers, so both longitudinal and latitudin…
Theoretical amplitudes of solar g-modes.
Andersen, B. N.
This work presents predictions on the amplitudes of solar g-modes. It is based on the assumption that convective overshoot into the convectively stable interior generates gravity waves. Based on this assumption it is possible to estimate values for the amplitude of the g-modes below the solar convection zone. Numerical simulations, giving the tran…
Searching for coronal plumes in ULYSSES observations of the far solar wind.
Livi, S.; Balogh, A.; Parenti, S. +4 more
In the past, from the analysis of data acquired by the Helios spacecrafts within distances <=1AU, some evidence has been found of the presence of coronal plumes in the solar wind. Ulysses observations offer a unique opportunity to search for plume remnants in the polar wind at larger distances. Pressure balanced structures (PBS), which might po…
