Solar Coronal Heating: Role of Kinetic and Inertial Alfvén Waves in Heating and Charged Particle Acceleration
Syed Ayaz, Gary P. Zank, Imran A. Khan +3
A comprehensive understanding of solar coronal heating and charged particle acceleration remains one of the most critical challenges in space and astrophysical plasma physics. In t…
Turbulence, Waves, and Taylor's Hypothesis for Heliosheath Observations
L. -L. Zhao, G. P. Zank, M. Opher +6
Magnetic field fluctuations measured in the heliosheath by the Voyager spacecraft are often characterized as compressible, as indicated by a strong fluctuating component parallel t…
Pickup Ion-Mediated Magnetic Reconnection in the Outer Heliosphere
M. Nakanotani, G. P. Zank, L. -L. Zhao
Pickup ions (PUIs) play a crucial role in the heliosphere, contributing to the mediation of large-scale structures such as the distant solar wind, the heliospheric termination shoc…
Structure and fluctuations of a slow ICME sheath observed at 0.5 au by the Parker Solar Probe
E. K. J. Kilpua, S. W. Good, M. Ala-Lahti +5
Sheaths ahead of interplanetary coronal mass ejections (ICMEs) are turbulent heliospheric structures. Knowledge of their structure and fluctuations is important for understanding t…
Turbulence in the Sub-Alfvénic Solar Wind
G. P. Zank, L. -L. Zhao, L. Adhikri +5
Parker Solar Probe (PSP) entered a region of the sub-Alfvenic solar wind during encounter 8 and we present the first detailed analysis of low-frequency turbulence properties in thi…
PSP/ISIS Observation of a Solar Energetic Particle Event Associated With a Streamer Blowout Coronal Mass Ejection During Encounter 6
T. Getachew, D. J. McComas, C. J. Joyce +21
In this paper we examine a low-energy SEP event observed by ISIS's Energetic Particle Instrument-Low (EPI-Lo) inside 0.18 AU on September 30, 2020. This small SEP event has…
Inertial range magnetic fluctuation anisotropy observed from PSP first seven orbits
L. -L. Zhao, G. P. Zank, L. Adhikari +1
Solar wind turbulence is anisotropic with respect to the mean magnetic field. Anisotropy leads to ambiguity when interpreting in-situ turbulence observations in the solar wind beca…
Detection of small magnetic flux ropes from the third and fourth Parker Solar Probe encounters
L. -L. Zhao, G. P. Zank, Q. Hu +22
We systematically search for magnetic flux rope structures in the solar wind to within the closest distance to the Sun of 0.13 AU, using data from the third and fourth orbits of th…
Cross Helicity of the November 2018 Magnetic Cloud Observed by the Parker Solar Probe
S. W. Good, E. K. J. Kilpua, M. Ala-Lahti +3
Magnetic clouds are large-scale transient structures in the solar wind with low plasma , low-amplitude magnetic field fluctuations, and twisted field lines with both ends often…
Turbulence Transport Modeling and First Orbit Parker Solar Probe (PSP) Observations
Laxman Adhikari, Gary P. Zank, Lingling Zhao +8
Parker Solar Probe (PSP) achieved its first orbit perihelion on November 6, 2018, reaching a heliocentric distance of about 0.165 au (35.55 R). Here, we study the evolution…
Identification of Magnetic Flux Ropes from Parker Solar Probe Observations during the First Encounter
L. -L. Zhao, G. P. Zank, L. Adhikari +17
The Parker Solar Probe (PSP) observed an interplanetary coronal mass ejection (ICME) event during its first orbit around the sun, among many other events. This event is analyzed by…
Observation of Energetic particles between a pair of Corotating Interaction Regions
Z. Wu, Y. Chen, G. Li +11
We report observations of the acceleration and trapping of energetic ions and electrons between a pair of corotating interaction regions (CIRs). The event occurred in Carrington Ro…
Study of Different Solar Cycle Variations of Solar Energetic Particles and Cosmic Rays by Despiking ACE/SIS Heavy-Ion Fluxes
G Qin, L. -L. Zhao
Cosmic Rays (CRs) include Galactic Cosmic Rays (GCRs) and Anomalous Cosmic Rays (ACRs). The CR flux data of protons and heavy-ions observed with spacecraft are often seriously cont…
Modulation of galactic cosmic rays during the unusual solar minimum between cycles 23 and 24
L. -L. Zhao, G. Qin, M. Zhang +1
During the recent solar minimum between cycles 23 and 24 (solar minimum ) the intensity of Galactic Cosmic Rays (GCRs) measured at the Earth was the highest ever recorde…
