Inertial-range Turbulence Anisotropy of the Young Solar Wind from Different Source Regions
Wenshuai Cheng, Ming Xiong, Yiming Jiao +4
We investigate the wavevector and variance anisotropies in the inertial range of the young solar wind observed by the Parker Solar Probe (PSP). Using the first 19 encounters of PSP…
On the Acceleration of the Young Solar Wind from Different Source Regions
Yiming Jiao, Ying D. Liu, Wenshuai Cheng +2
The acceleration of the young solar wind is studied using the first 17 encounters of Parker Solar Probe. We identify wind intervals from different source regions: coronal hole (CH)…
Origin and Properties of the Near Subsonic Solar Wind Observed by Parker Solar Probe
Wenshuai Cheng, Ying D. Liu, Hao Ran +3
We identify and examine the solar wind intervals near the sonic critical point (i.e., ) observed by the Parker Solar Probe (PSP). The near subsonic wind intervals show…
The Alpha-Proton Differential Flow in the Alfvénic Young Solar Wind: From Sub-Alfvénic to Super-Alfvénic
Hao Ran, Ying D. Liu, Chong Chen +1
Data obtained from Parker Solar Probe (PSP) since 2021 April have shown the first in situ observation of the solar corona, where the solar wind is formed and accelerated. Here we i…
Direct In Situ Measurements of a Fast Coronal Mass Ejection and Associated Structures in the Corona
Ying D. Liu, Bei Zhu, Hao Ran +6
We report on the first direct in situ measurements of a fast coronal mass ejection (CME) and shock in the corona, which occurred on 2022 September 5. In situ measurements from the…
Properties of Steady Sub-Alfvénic Solar Wind in Comparison with Super-Alfvénic Wind from Measurements of Parker Solar Probe
Yiming Jiao, Ying D. Liu, Hao Ran +1
We identify more than ten 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-…
