Inner-heliospheric Signatures of Steadily Declining Solar Magnetic Fields and Their Possible Implications

The Astrophysical Journal
We examined solar photospheric magnetic fields for the solar cycles 21–25, covering the period 1975–2024. The unsigned photospheric magnetic fields at low latitudes (0°–45°), known as solar toroidal fields, showed a solar cycle variation with the total ...

Direct comparison of Viking 2.3-GHz signal phase fluctuation and columnar electron density between 2 and 160 solar radii [PDF]

The relationship between solar wind induced signal phase fluctuation and solar wind columnar electron density has been the subject of intensive analysis during the last two decades.

Relevance of Murchison Widefield Array Interplanetary Scintillation Observations to Heliospheric Transient Catalogs

Space Weather
We have conducted a comprehensive comparison of interplanetary scintillation (IPS) observations taken by the Murchison Widefield Array (MWA) with several heliospheric transient event catalogs, over a time period of 7 months during solar minimum.

Dynamics of Slow Solar Wind Emerging from an Equatorial Coronal Hole

The Astrophysical Journal
We present a three-dimensional reduced magnetohydrodynamics model to depict turbulence induced by Alfvén waves within the slow solar wind originating from an open magnetic field positioned in a coronal hole near the solar equator.

Different Polarized Components of the Quasar 3C 286 Revealed by FAST

The Astrophysical Journal
3C 286, a well-known radio calibrator, exhibits stability in both total flux density and polarization parameters. However, its stable and luminous interstellar radio signal may encounter interplanetary scintillation (IPS) due to density irregularities in
