    Assessing the Influence of Input Magnetic Maps on Global Modeling of the Solar Wind and CME‐Driven Shock in the 2013 April 11 Event by Meng Jin, Nariaki V. Nitta, Christina M. S. Cohen

    Published 2022-03-01
    “…In this study, using the Alfvén wave solar model, we quantitatively assess the influence of the magnetic field map input (synoptic/diachronic vs. synchronic magnetic maps) on the global modeling of the solar wind and the CME‐driven shock in the 11 April 2013 solar energetic particle event. …”

    TR Jets above Magnetic X-Type Null Points by Ehsan Tavabi, Mehri Heidari, Azam Mollatayefeh

    Published 2023-11-01
    “…In addition to the whip-like behavior, null-point motions in the reconnection site can excite transversal oscillation along the magnetical dense Jets, which is called the kink mode wave, and also this mode can evolve into Alfven wave after its propagation into the more homogeneous medium. …”

    Validation of Simulated Statistical Characteristics of Magnetosphere‐Ionosphere Coupling in Global Geospace Simulations Over an Entire Carrington Rotation by Qianfeng Yin, Kevin H. Pham, Junjie Chen, Binzheng Zhang

    Published 2024-06-01
    “…The distribution of the simulated Alfvénic Poynting flux is consistent with that observed by the FAST satellite in the dispersive Alfvén wave regime. These M‐I coupling characteristics are also binned by the Kp indices, indicating that the Kp dependence of these patterns in the M‐I model is more effective than the empirical models within the Carrington Rotation. …”

    Multi-observatory Study of Young Stellar Energetic Flares (MORYSEF): No Evidence for Abnormally Strong Stellar Magnetic Fields after Powerful X-Ray Flares by Konstantin V. Getman, Oleg Kochukhov, Joe P. Ninan, Eric D. Feigelson, Vladimir S. Airapetian, Abygail R. Waggoner, L. Ilsedore Cleeves, Jan Forbrich, Sergio A. Dzib, Charles J. Law, Christian Rab, Daniel M. Krolikowski

    Published 2025-01-01
    “…These deviations likely stem from the fact that powerful flares are driven by magnetic reconnection, while baseline X-ray emission may involve less efficient mechanisms like Alfvén wave heating. Our results also indicate a preference for dipolar magnetic loops in PMS flares, consistent with Zeeman–Doppler imaging of fully convective stars. …”
