    Nonthermal Signatures of Radiative Supernova Remnants. II. The Impact of Cosmic Rays and Magnetic Fields by Rebecca Diesing, Siddhartha Gupta

    Published 2025-01-01
    “…We also use a self-consistent model of particle acceleration to estimate the nonthermal emission from these modified SNRs and demonstrate that, for reasonable CR acceleration efficiencies and magnetic field strengths, the nonthermal signatures of shell formation can all but disappear. …”

    Time-dependent Acceleration and Escape of Charged Particles at Traveling Shocks in the Near-Sun Environment by Thomas M. Do, Federico Fraschetti, Jozsef Kota, Joe Giacalone, Christina M. S. Cohen, David J. McComas

    Published 2025-01-01
    “…The average timescale for particle acceleration at various heliocentric distances, from 1 au down to the inner heliosphere (<0.1 au), is shorter than in the no-escape case, as higher energy particles have a shorter time to accelerate before completely leaving the system into the upstream medium. …”

    Radial Evolution of Interplanetary Shock Properties with Heliospheric Distance: Observations from Parker Solar Probe by Oksana Kruparova, Adam Szabo, Lan K. Jian, František Němec, Jana Šafránková, Zdeněk Němeček, Jacob Pasanen, Ayris Narock, Vratislav Krupar

    Published 2025-01-01
    “…These findings provide new insights into the dynamic processes governing shock evolution in the inner heliosphere, including scenarios where the near-radial magnetic field geometry may lead to predominantly quasi-parallel shock configurations and thus affect near-Sun particle acceleration efficiency. We also provide strong evidence for the existence of slow-mode shocks near the Sun, contributing to the understanding of shock formation and evolution in the inner heliosphere.…”
