Abstract Very low frequency (VLF) waves (about 3–30 kHz) in the Earth’s magnetosphere interact strongly with energetic electrons and are a key element in controlling dynamics of the Van Allen radiation belts. Bistatic very low frequency (VLF) tra

Formation of the Transition Region for the Quiet Sun
Autor: Paul Song, Jiannan Tu, David B. Wexler
Publikováno v: The Astrophysical Journal Letters, Vol 948, Iss 1, p L4 (2023)
We propose a partially ionized collisional two-fluid model of the formation of the transition region between the cool dense chromosphere and hot tenuous corona for the quiet Sun. The chromosphere is treated as an isothermal gravity-bound two-fluid st

Slow solar wind acceleration through the middle corona: Spacecraft radio studies
Autor: David B. Wexler, Jason E. Kooi, Elizabeth A. Jensen, Paul Song
Publikováno v: Frontiers in Astronomy and Space Sciences, Vol 9 (2022)
The “Middle Corona”, defined by recent consensus as the region spanning 1.5–6 solar radii (R⊙, heliocentric), is an important zone through which several structural and dynamic changes occur in coronal streamer regions. Among these is a regime

Investigating a Solar Wind Stream Interaction Region using Interplanetary Spacecraft Radio Signals: A Magnetohydrodynamic Simulation Study
Autor: David B. Wexler, Ward B. Manchester, Lan K. Jian, Lynn B. Wilson III, Natchimuthuk Gopalswamy, Paul Song, Jason E. Kooi, Bart van der Holst, Elizabeth A. Jensen
Publikováno v: The Astrophysical Journal, Vol 955, Iss 2, p 90 (2023)
Stream interaction regions (SIRs) are spiral heliospheric structures that arise at the interface between fast and preceding slow solar wind regions. SIR enhancements of density and magnetic field intensity, often with magnetic polarity inversion, are

Whistler-Mode Radiation From a Dipole Antenna in Cold Magnetized Plasma
Autor: Jiannan Tu, W. R. Johnston, Bodo W. Reinisch, Ivan Galkin, Paul Song
Publikováno v: IEEE Transactions on Antennas and Propagation. 70:2915-2927
We treat whistler mode radiation from a dipole antenna in a cold magnetized plasma based on the Fresnel zone construction theory. Radiated waves from the antenna with different propagation directions interfere in space. Regions of enhanced waves are
