Injection and propagation of solar protons to high heliospheric latitudes: Ulysses Ket observations
Kunow, H.; Heber, B.; Müller-Mellin, R. +3 more
The Ulysses spacecraft at high heliographic latitudes has detected eight large solar energetic particle events during the recent solar maximum in 2000 and 2001 years. These events are easily identified with famous episodes of the solar activity and the corresponding SEP events near the Earth. Analyzing the absolute intensities of ∼40 100 MeV proto…
Modeling accelerated pick-up ion distributions at an interplanetary shock
Baring, Matthew G.; Summerlin, Errol J.
The acceleration of interstellar pick-up ions as well as solar wind species has been observed at a multitude of interplanetary (IP) shocks by different spacecraft. The efficiency of injection of the pick-up ion component differs from that of the solar wind, and is expected to be strongly enhanced at highly oblique and quasi-perpendicular shock eve…
Wave acceleration of the fast solar wind
Ofman, Leon
Observations show that the solar wind exhibits two modes of outflow: the slow (∼400 km s -1), high density, highly variable wind that emerges from equatorial solar regions, and the high latitude, fast (∼800 km s -1), low density, steady solar wind. The bi-modal solar wind outflow is most evident near minima of solar activity.…
