A Major Geomagnetic Storm in 2024 October Linked to Sympathetic CME--Prominence Eruptions
Rui Wang, Huidong Hu, Xiaowei Zhao +11
Improving predictions of the geomagnetic impact of coronal mass ejections (CMEs) requires understanding how solar source properties relate to in-situ measurements at Earth. However…
Proton Temperature Anisotropy Across Interplanetary Shocks: A Statistical Analysis with WIND observations
Zeping Jin, Lingling Zhao, Xingyu Zhu +6
Interplanetary (IP) shocks efficiently modify the proton temperature anisotropy of the solar wind. Analyzing ~800 IP shocks observed by the Wind spacecraft from 1997-2024, we prese…
Lateral Deformation of Large-scale Coronal Mass Ejections during the Transition from Non-radial to Radial Propagation
Huidong Hu, Chong Chen, Yiming Jiao +4
Many coronal mass ejections (CMEs) initially propagate non-radially, and then transition to radial propagation in the corona. This directional transition is a significant process t…
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…
Multi-scale Energy Release Events in the Quiet Sun: A Possible Source for Coronal Heating
Rui Wang, Yiming Jiao, Xiaowei Zhao +1
The coronal heating problem remains one of the most challenging questions in solar physics. The energy driving coronal heating is widely understood to be associated with convective…
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)…
