ACR Proton Acceleration Associated with Reconnection Processes beyond the Heliospheric Termination Shock

摘要: One of the curious observations from Voyagers is that intensity anomalous cosmic rays (ACRs) did not peak at heliospheric termination shock (HTS) but instead a short distance (within ~1 au) downstream HTS. possible explanation interaction wavy current sheet with HTS enhances magnetic reconnection and generates numerous small-scale flux ropes in heliosheath immediately Charged particles are accelerated this region due to Fermi acceleration electric field. In work, we provide observational evidence presence just using wavelet analysis reduced helicity Grad–Shafranov reconstruction techniques. The Zank et al. kinetic transport theory for propagating through islands employed fit observed energetic proton intensities post-HTS region. Our modeling results agree reasonably well observations, which suggests stochastic via processes can explain ACR beyond
