Data-constrained Magnetohydrodynamic Simulation of the Global Solar Corona Including Solar Wind Effects within 2.5 R⊙

The Astrophysical Journal
Total solar eclipses (TSEs) provide a unique opportunity to observe the large-scale solar corona. The solar wind plays an important role in forming the large-scale coronal structure, and magnetohydrodynamic (MHD) simulations are used to reproduce it for ...

Inertial-range Turbulence Anisotropy of the Young Solar Wind from Different Source Regions

The Astrophysical Journal Letters
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 measurements, we identify the young solar wind from different source ...

On the Acceleration of the Young Solar Wind from Different Source Regions

The Astrophysical Journal Letters
The acceleration of the young solar wind is studied using the first 17 encounters of the Parker Solar Probe. We identify wind intervals from different source regions: coronal hole (CH) interiors, streamers, and low-Mach-number boundary layers (LMBLs), i ...

A study of the physical mechanisms for filament eruption and coronal mass ejection via numerical simulation [PDF]

During this period of performance (1 Jan. 1992 - 31 Dec. 1992), the investigation of the following tasks was accomplished: (1) application of the Non-linear Force-free Field (NLFF) Model to study the active region evolution; (2) coronal dynamical ...

Radial Evolution of a Density Structure within a Solar Wind Magnetic Sector Boundary

The Astrophysical Journal
This study focuses on a radial alignment between Parker Solar Probe (PSP) and Solar Orbiter (SolO) on 2021 April 29 (during a solar minimum), when the two spacecraft were, respectively, located at ∼0.075 and ∼0.9 au from the Sun. A previous study of this
