Variation in Path Lengths of Turbulent Magnetic Field Lines and Solar Energetic Particles
Wirin Sonsrettee, Piyanate Chuychai, Achara Seripienlert +5
Modeling of time profiles of solar energetic particle (SEP) observations often considers transport along a large-scale magnetic field with a fixed path length from the source to th…
Magnetic Field Line Separation by Random Ballistic Decorrelation in Transverse Magnetic Turbulence
Chutima Yannawa, Peera Pongkitiwanichakul, David Ruffolo +2
The statistics of the magnetic field line separation provide insight into how a bundle of field lines spreads out and the dispersion of non-thermal particles in a turbulent environ…
Role of Parallel Solenoidal Electric Field on Energy Conversion in 2.5D Decaying Turbulence with a Guide Magnetic Field
Peera Pongkitiwanichakul, David Ruffolo, Fan Guo +5
We perform 2.5D particle-in-cell simulations of decaying turbulence in the presence of a guide (out-of-plane) background magnetic field. The fluctuating magnetic field initially co…
Domains of Magnetic Pressure Balance in Parker Solar Probe Observations of the Solar Wind
David Ruffolo, Nawin Ngampoopun, Yash R. Bhora +4
The Parker Solar Probe (PSP) spacecraft is performing the first in situ exploration of the solar wind within 0.2 au of the Sun. Initial observations confirmed the Alfvénic nature o…
Solar Orbiter Observations of the Kelvin-Helmholtz Instability in the Solar Wind
R. Kieokaew, B. Lavraud, Y. Yang +17
The Kelvin-Helmholtz instability (KHI) is a nonlinear shear-driven instability that develops at the interface between shear flows in plasmas. KHI has been inferred in various astro…
Magnetic Field Line Random Walk and Solar Energetic Particle Path Lengths: Stochastic Theory and PSP/ISoIS Observation
R. Chhiber, W. H. Matthaeus, C. M. S. Cohen +21
Context:In 2020 May-June, six solar energetic ion events were observed by the Parker Solar Probe/ISoIS instrument suite at 0.35 AU from the Sun. From standard velocity-dispersion a…
