Direct Measurement of Diffusion Coefficients: Evidence for Diffusive Stochastic Heating in Collisionless Plasmas
Tamar Ervin, Trevor A. Bowen, Alfred Mallet +7
Open questions in collisionless plasma dissipation can be addressed using space-based observations in different astrophysical environments, with implications for both astrophysical…
Parker Solar Probe observations of solar energetic particle (SEP) events with inverse velocity arrival (IVA) features
Zigong Xu, C. M. S. Cohen, R. A. Leske +21
In SEP events, velocity dispersion (VD) is characterized by the earlier arrival of faster, higher-energy particles relative to slower ones, assuming negligible acceleration time an…
Quantifying the Effects of Parameters in Widespread SEP Events with EPREM
Matthew A. Young, Bala Poduval
The Energetic Particle Radiation Environment Model (EPREM) solves the focused transport equation (FTE) on a Lagrangian grid in a frame co-moving with the solar wind plasma and simu…
Successive interacting coronal mass ejections: How to create a perfect storm?
Gordon J. Koehn, Ravindra T. Desai, Emma E. Davies +3
Coronal mass ejections (CMEs) are the largest type of eruptions on the Sun and the main driver of severe space weather at the Earth. In this study, we implement a force-free sphero…
Predicting the Magnetic Fields of a Stealth CME Detected by Parker Solar Probe at 0.5 AU
Erika Palmerio, Christina Kay, Nada Al-Haddad +5
Stealth coronal mass ejection (CMEs) are eruptions from the Sun that are not associated with appreciable low-coronal signatures. Because they often cannot be linked to a well-defin…
Categorization of Coronal Mass Ejection Driven Sheath Regions: Characteristics of STEREO Events
T. M. Salman, N. Lugaz, R. M. Winslow +3
We present a comprehensive statistical analysis of 106 sheath regions driven by coronal mass ejections (CMEs) and measured near 1 AU. Using data from the STEREO probes, this extend…
Coronal Hole Detection and Open Magnetic Flux
J. A. Linker, S. G. Heinemann, M. Temmer +14
Many scientists use coronal hole (CH) detections to infer open magnetic flux. Detection techniques differ in the areas that they assign as open, and may obtain different values for…
Interplanetary magnetic flux rope observed at ground level by HAWC
S. Akiyama, R. Alfaro, C. Alvarez +59
We report the ground-level detection of a Galactic Cosmic-Ray (GCR) flux enhancement lasting 17 hr and associated with the passage of a magnetic flux rope (MFR) over the Ear…
Examining Periodic Solar Wind Density Structures Observed in the SECCHI Heliospheric Imagers
Nicholeen M. Viall, Harlan E. Spence, Angelos Vourlidas +1
We present an analysis of small-scale, periodic, solar-wind density enhancements (length-scales as small as \approx 1000 Mm) observed in images from the Heliospheric Imager (HI) ab…
The Turbulent Heating Rate in Strong MHD Turbulence with Nonzero Cross Helicity
Benjamin D. G. Chandran, Eliot Quataert, Gregory G. Howes +2
Different results for the cascade power in strong, incompressible MHD turbulence with nonzero cross helicity appear in the literature. In this paper, we discuss the conditions unde…
Scale dependent alignment between velocity and magnetic field fluctuations in the solar wind and comparisons to Boldyrev's phenomenological theory
J. J. Podesta, A. Bhattacharjee, B. D. G. Chandran +2
(Abridged abstract) A theory of incompressible MHD turbulence recently developed by Boldyrev predicts the existence of a scale dependent angle of alignment between velocity and mag…
