Current sheets, magnetic islands, and associated particle acceleration in the solar wind as observed by Ulysses near the ecliptic plane
(IOP Publishing, 2019)Recent studies of particle acceleration in the heliosphere have revealed a new mechanism that can locally energize particles up to several MeV nucleon–1. Stream–stream interactions, as well as the heliospheric current sheet ... -
A Fisk-Parker hybrid heliospheric magnetic field with a solar-cycle dependence
(IOP Publishing, 2008)We present a refinement of the Fisk-Parker hybrid field of Burger and Hitge which now includes a region bordering the solar rotational equator where magnetic field footpoint motion occurs only through diffusive reconnection. ... -
Modulation of galactic cosmic ray protons and electrons during an unusual solar minimum
(IOP Publishing, 2009)During the latest Ulysses out-of-ecliptic orbit the solar wind density, pressure, and magnetic field strength have been the lowest ever observed in the history of space exploration. Since cosmic ray particles respond to ... -
Non-axisymmetric perpendicular diffusion of charged particles and their transport across tangential magnetic discontinuities
(IOP Publishing, 2016)We investigate the transport of charged particles across magnetic discontinuities, focusing specifically on stream interfaces associated with co-rotating interaction regions in the solar wind. We argue that the magnetic ...
