The Solar Wind Energy Flux [PDF]
Solar Physics, 2012 The solar-wind energy flux measured near the ecliptic is known to be independent of the solar-wind speed. Using plasma data from Helios, Ulysses, and Wind covering a large range of latitudes and time, we show that the solar-wind energy flux is independent of the solar-wind speed and latitude within 10%, and that this quantity varies weakly over the ...

Solar Wind and its Evolution [PDF]
Earth, Planets and Space, 2011 By using our previous results of magnetohydrodynamical simulations for the solar wind from open flux tubes, I discuss how the solar wind in the past is different from the current solar wind.

Journal of Research of the National Bureau of Standards, Section D: Radio Propagation, 1961 >Hydrodynamic expansion of the solar corona is the basis for solar corpuscular radiation. The quiet day coronal temperatures of 1 to 2 x 10/sup 6/ deg K yield a solar wind of several hundred km/sec and a density of 5 to 50 particles/cm/sup 3/ at the orbit of Earth.

In-situ Switchback Formation in the Expanding Solar Wind [PDF]
Astrophysical Journal, 2020 Recent near-Sun solar-wind observations from Parker Solar Probe have found a highly dynamic magnetic environment, permeated by abrupt radial-field reversals, or “switchbacks.” We show that many features of the observed turbulence are reproduced by a ...

The model for non-Abelian field topology for the multilayer fractional quantum anomalous Hall device
Frontiers in Physics, 2022 From the recent empirical discovery of the quantum anomalous Hall effect (QAHE), the interaction of the particle with spin–orbit coupling (SOC) plays an essential role in the cause of the QAHE, which includes three terms: external, internal, and chiral ...

Physical Review Letters, 2022 We study the solar emission of light dark sector particles that self-interact strongly enough to self-thermalize. The resulting outflow behaves like a fluid which accelerates under its own thermal pressure to highly relativistic bulk velocities in the solar system.

Pixel-Based Image Processing for CIE Standard Sky Classification through ANN
Complexity, 2021 Digital sky images are studied for the definition of sky conditions in accordance with the CIE Standard General Sky Guide. Likewise, adequate image-processing methods are analyzed that highlight key image information, prior to the application of ...

Algorithm for frequency capture and rectification in a low-orbit satellite IoT communication network
Mathematical Biosciences and Engineering, 2021 In satellite communication systems, due to relative motion between satellites and that between satellites and the ground, the resulting Doppler frequency offset adversely affects communication synchronization.

Mathematical Biosciences and Engineering, 2022 This paper investigates a left-hand circularly polarized (LHCP) antenna and a right-hand circularly polarized (RHCP) antenna on LEO Satellite, which is based on the phase-tuning metasurface. We overcome its inherent limitations in size, weight and power,
