Session ID#: 13823

Session Description:
Magnetic flux ropes occur over a wide range of spatial scales throughout the heliosphere. Large-scale flux ropes are usually associated with large-scale magnetic cloud structures inside interplanetary coronal mass ejections (ICMEs). These structures are observed to contribute to Forbush decreases in solar energetic particles and low-energy cosmic rays. Evidence exists for small-scale flux rope formation from turbulent magnetic reconnection at primary current sheets including the heliospheric current sheet (HCS), current sheets formed in the post-shock flow of rippled shocks, at the leading and trailing edges of CME structures, inside corotating interaction regions (CIRs), and in the Earth’s magnetotail and heliopause.  Enhanced fluxes of energetic particles were detected in these regions which might indicate particle 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 and associated processes throughout the heliosphere.
