DescriptionMagnetic flux ropes in the heliosphere are usually associated with large-scale magnetic cloud structures inside interplanetary coronal mass ejections (CMEs) behind traveling shocks. However, a less well understood second class of smaller-scale flux ropes were also identified in observations. It seems that these flux ropes arise mostly from turbulent reconnection in primary large-scale current sheets, the heliospheric current sheet (HCS), primary current sheets at the leading and trailing edges of CME structures, the Earth’s magnetopause and magnetotail, and heliopause. MHD simulations suggest that they should exist everywhere in the solar wind. Enhanced fluxes of energetic particles were detected recently in multiple small-scale flux ropes near the HCS, suggesting particles acceleration by multiple flux-rope dynamics as simulations predict. We solicit observational, theoretical, and simulation contributions that will shed light on the fundamental physics of flux ropes of all scales throughout the heliosphere including particle energization and other associated processes.
