Alfvénic wind observed by the Parker Solar Probe (PSP), and the morphology of the Alfvénic …

Properties of steady sub-Alfvénic solar wind in comparison with super-Alfvénic wind from parker solar probe measurements

Y Jiao, YD Liu, H Ran, W Cheng - The Astrophysical Journal, 2023 - iopscience.iop.org
We identify more than 10 steady sub-Alfvénic solar wind intervals from the measurements of
the Parker Solar Probe (PSP) from encounter 8 to encounter 14. An analysis of these sub …

Origin and Properties of the Near-subsonic Solar Wind Observed by Parker Solar Probe

W Cheng, YD Liu, H Ran, Y Jiao… - The Astrophysical …, 2024 - iopscience.iop.org
We identify and examine the solar wind intervals near the sonic critical point (ie, MS∼ 1)
observed by the Parker Solar Probe. The near-subsonic wind intervals show similar …

PSP Observations of a Slow Shock Pair Bounding a Large‐Scale Plasmoid/Macro Magnetic Hole

Z Zhou, X Xu, P Zuo, Y Wang, L Wang… - Geophysical …, 2022 - Wiley Online Library
