Connecting Solar Wind Velocity Spikes Measured by Solar Orbiter and Coronal Brightenings Observed by SDO

The Astrophysical Journal Letters
The Parker Solar Probe's discovery that magnetic switchbacks and velocity spikes in the young solar wind are abundant has prompted intensive research into their origin(s) and formation mechanism(s) in the solar atmosphere.

Magnetic Connectivity in the Time-dependent Corona and Heliosphere

The Astrophysical Journal Letters
Magnetic flux fills the heliosphere, expands outward from the solar corona, and is fundamentally related to the structure and dynamics of the solar corona and solar wind.

Identifying Coronal Sources of L1 Solar Wind Disturbances Using the Fisk Heliospheric Magnetic Field and Potential Field Extrapolations during Three Solar Minima

The Astrophysical Journal
The solar minima between solar cycles 22–23, 23–24, and 24–25 are the best observed minima on record. In situ solar wind and interplanetary magnetic field measurements by the Wind and ACE spacecraft at L1 with 1 hr cadence are explored using wavelet ...

Acceleration of the Fast Solar Wind by Solitary Waves in Coronal Holes

, 2000
The purpose of this investigation is to develop a new model for the acceleration of the fast solar wind by nonlinear, time-dependent multidimensional MHD simulations of waves in solar coronal holes.

Coronal Holes

, 2008
Coronal holes are regions of low-density plasma on the Sun that have magnetic fields that open freely into interplanetary space. During times of low solar activity, coronal holes cover the north and south polar caps of the Sun. During more active periods,
