Observations of Mini Coronal Dimmings Caused by Small-scale Eruptions in the Quiet Sun
Rui Wang, Ying D. Liu, Xiaowei Zhao +1
Small-scale eruptions could play an important role in coronal heating, generation of solar energetic particles (SEPs), and mass source of the solar wind. However, they are poorly o…
On the Generation and Evolution of Switchbacks and the Morphology of Alfvénic Transition: Low Mach-number Boundary Layers
Ying D. Liu, Hao Ran, Huidong Hu +1
We investigate the generation and evolution of switchbacks (SBs), the nature of the sub-Alfvénic wind observed by Parker Solar Probe (PSP), and the morphology of the Alfvénic trans…
Spectroscopic and Imaging Observations of Spatially Extended Magnetic Reconnection in the Splitting of a Solar Filament Structure
Huidong Hu, Ying D. Liu, Lakshmi Pradeep Chitta +2
On the Sun, Doppler shifts of bidirectional outflows from the magnetic-reconnection site have been found only in confined regions through spectroscopic observations. Without spatia…
Multispacecraft Remote Sensing and In Situ Observations of the 2020 November 29 Coronal Mass Ejection and Associated Shock: From Solar Source to Heliospheric Impacts
Chong Chen, Ying D. Liu, Bei Zhu
We investigate the source eruption, propagation and expansion characteristics, and heliospheric impacts of the 2020 November 29 coronal mass ejection (CME) and associated shock, us…
Analysis of the distribution, rotation and scale characteristics of solar wind switchbacks: comparison between the first and second encounters of Parker Solar Probe
Mingming Meng, Ying D. Liu, Chong Chen +1
The S-shaped magnetic structure in the solar wind formed by the twisting of magnetic field lines is called a switchback, whose main characteristics are the reversal of the magnetic…
MMS direct observations of kinetic-scale shock self-reformation
Zhongwei Yang, Ying D. Liu, Andreas Johlander +6
Studies of shocks have long suggested that a shock can undergo cyclically self-reformation in a time scale of ion cyclotron period. This process has been proposed as a primary mech…
Determination of Solar Wind Angular Momentum and Alfvén Radius from Parker Solar Probe Observations
Ying D. Liu, Chong Chen, Michael L. Stevens +1
As fundamental parameters of the Sun, the Alfvén radius and angular momentum loss determine how the solar wind changes from sub-Alfvénic to super-Alfvénic and how the Sun spins dow…
PIC simulations of microinstabilities and waves at near-Sun solar wind perpendicular shocks: Predictions for Parker Solar Probe and Solar Orbiter
Zhongwei Yang, Ying D. Liu, Shuichi Matsukiyo +6
Microinstabilities and waves excited at moderate-Mach-number perpendicular shocks in the near-Sun solar wind are investigated by full particle-in-cell (PIC) simulations. By analyzi…
Characteristics and Importance of "ICME-in-Sheath" Phenomenon and Upper Limit for Geomagnetic Storm Activity
Ying D. Liu, Chong Chen, Xiaowei Zhao
As an important source for large geomagnetic storms, an "ICME-in-sheath" is a completely shocked interplanetary coronal mass ejection (ICME) stuck in the sheath between a shock and…
Effects of Coronal Density and Magnetic Field Distributions on a Global Solar EUV Wave
Huidong Hu, Ying D. Liu, Bei Zhu +4
We investigate a global extreme-ultraviolet (EUV) wave associated with a coronal mass ejection (CME)-driven shock on 2017 September 10. The EUV wave is transmitted by north- and so…
Successive Two-sided loop Jets Caused by Magnetic Reconnection between Two adjacent Filamentary Threads
Zhanjun Tian, Yu Liu, Yuandeng Shen +4
We present observational analysis of two successive two-sided loop jets observed by the ground-based New Vacuum Solar Telescope (NVST) and the space-borne Solar Dynamics Observator…
Propagation Characteristics of Two Coronal Mass Ejections From the Sun Far into Interplanetary Space
Xiaowei Zhao, Ying D. Liu, Huidong Hu +1
Propagation of coronal mass ejections (CMEs) from the Sun far into interplanetary space is not well understood due to limited observations. In this study we examine the propagation…
Using Coordinated Observations in Polarised White Light and Faraday Rotation to Probe the Spatial Position and Magnetic Field of an Interplanetary Sheath
Ming Xiong, Jackie A. Davies, Xueshang Feng +4
Coronal mass ejections (CMEs) can be continuously tracked through a large portion of the inner heliosphere by direct imaging in visible and radio wavebands. White-light (WL) signat…
