Solar Origins of Short-Term Periodicities in Near-Earth Solar Wind and Interplanetary Magnetic Field

Applied Sciences
This study investigates the solar origins of short-term periodicities in the near-Earth solar wind and interplanetary magnetic field (IMF) using long-term observations (1995–2024) and Potential Field Source Surface modeling.

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.

Elemental Abundances at Coronal Hole Boundaries as a Means to Investigate Interchange Reconnection and the Solar Wind

The Astrophysical Journal
The origin of the slow solar wind is not well understood, unlike the fast solar wind that originates from coronal holes. In situ elemental abundances of the slow solar wind suggest that it originates from initially closed field lines that become open ...

Microwave Bright Points with Multiple Periodic Oscillations in the Solar Polar Coronal Hole during Solar Cycle Minimum

The Astrophysical Journal
During solar cycle minimum, polar coronal holes show a prominent radio brightening cap. The analysis of polar microwave enhanced radiation in polar coronal holes is helpful for understanding the magnetic field characteristics and the origin of the solar ...

Solar Wind Acceleration in Coronal Holes

, 2002
This paper reviews the current state of our understanding of high-speed solar wind acceleration in coronal holes. Observations by SOHO, coupled with interplanetary particle measurements going back several decades, have put strong constraints on possible explanations for how the protons, electrons, and minor ions receive their extreme kinetic properties.

CORONAL HOLES AND THE HIGH-SPEED SOLAR WIND

, 2008
. Coronal holes are the lowest density plasma components of the Sun’s outer atmosphere, and are associated with rapidly expanding magnetic fields and the acceleration of the high-speed solar wind.

Cosmic ray response to CMEs related with solar flares and coronal holes

, 1993
413-414The results of an analysis of the associations of coronal mass ejections (CMEs) with solar flares and coronal holes are presented. The above associations are examined by assuming that the cosmic ray response to the CMEs related with solar flares ...

Responses of a Coronal Hole to a Fast Flare-driven Coronal Wave

The Astrophysical Journal Letters
Coronal waves, significant solar phenomena, act as diagnostic tools for scientists studying solar atmosphere properties. Here, we present a novel observation detailing how a coronal wave event, associated with an X5.0 class flare, influenced the ...

Propagating MHD Waves in Coronal Holes

, 2010
Coronal holes are the coolest and darkest regions of the upper solar atmosphere, as observed both on the solar disk and above the solar limb. Coronal holes are associated with rapidly expanding open magnetic fields and the acceleration of the high-speed ...
