Charge States of Energetic Particles from Corotating Interaction Regions as Constraints on Their Source
Since the discovery of large (factor of greater than 1000) enhancements of singly ionized helium in corotating interaction regions (CIRs), it has become clear that low charge state ions from interstellar neutrals or other heliospheric sources can be preferentially injected into the energetic particle population. The large enhancements in suprathermal and energetic He` suggest that low charge st...
متن کاملSTEREO and ACE Observations of Energetic Particles from Corotating Interaction Regions
Since early 2007, significant particle enhancements due to corotating interaction regions (CIRs) have regularly appeared at 1 AU without any appreciable contamination from solar energetic particles (SEPs). In 2009 the prevalence of CIRs diminished as the maximum speed of the high speed solar wind streams in the ecliptic decreased along with the tilt of the heliospheric current sheet. Observatio...
متن کاملCorotating Interaction Regions and clumping
Discrete Absorption Components (DACs) seen in ultraviolet lines are one of the clearest indicators of large-scale structure in the winds of hot stars. Cranmer & Owocki (1996) attributed these DACs to Corotating Interaction Regions (CIRs) which are formed when slow and fast streams collide in the wind. In their model, CIRs are produced by introducing a spot on the stellar surface. The spot can l...
