Summary:
1. Science Goals and Objectives. The main goals of this project are: (i) Investigation of the fundamental physics of how, and to what extent, dynamic small-scale magnetic flux ropes (SMFRs), observed to occur in the vicinity of shocks driven by coronal mass ejections (CMEs) and their interplanetary counterparts (ICMEs), produce suprathermal particle populations through efficient SMFR acceleration. (ii) Gain an understanding of how these populations act as seed particles for the diffusive shock acceleration (DSA) of solar energetic particles (SEPs) at CME/ICME-driven shocks between the solar corona and Earth orbit. This involves the following main science objectives: (1) Determination of the relative efficiency of various theoretically identified competing 1st and 2nd order Fermi acceleration SFMR mechanisms in producing suprathermal ion and electron populations. (2) Estimation of the probability of these suprathermal particle populations in forming a significant seed population for injection into DSA of SEPs at CME/ICME-driven shocks. (3) Study the existence of a competition between SMFR acceleration and DSA above a threshold energy which might modify the spectral features and time profiles of SEPs undergoing DSA. (4) Deduction of the background suprathermal spectrum in the corona.Performance Year | Reference | Investigation Type | Actions |
