Free-Boundary Axisymmetric MHD Equilibrium
The calculation of equilibrium conditions is a common task in the study and modeling of magnetic-confinement experiments for con- trolled nuclear fusion, in which a high-temperature plasma is confined in a finite region ...
The NSF/DOE Partnership in Basic Plasma Science & Engineering at 20: Report on the Anniversary Workshop
A workshop recognizing the 20th anniversary of the NSF/DOE Partnership in Basic Plasma Science and Engineering was held at NSF on January 9-11, 2017. The workshop demonstrated some of the remarkable research and broader ...
Simulation studies of a recorder in three dimensions
The aeroacoustics of a recorder are explored using a direct numerical simulation based on the Navier–Stokes equations in three dimensions. The qualitative behavior is studied using spatial maps of the air pressure and ...
Explaining the Railsback stretch in terms of the inharmonicity of piano tones and sensory dissonance
The perceptual results of Plomp and Levelt for the sensory dissonance of a pair of pure tones are used to estimate the dissonance of pairs of piano tones. By using the spectra of tones measured for a real piano, the effect ...
Aeroacoustics of wind musical instruments
This is a record of a dataset deposit.
Ring/Shell Ion Distributions at Geosynchronous Orbit
One year's worth of plasma observations from geosynchronous orbit is examined for ion distributions that may simultaneously be subject to the ion Bernstein (IB) instability (generating fast magnetosonic waves) and the ...
Cross-scale observations of the 2015 St. Patrick's day storm: THEMIS, Van Allen Probes, and TWINS
We present cross-scale magnetospheric observations of the 17 March 2015 (St. Patrick's Day) storm, by Time History of Events and Macroscale Interactions during Substorms (THEMIS), Van Allen Probes (Radiation Belt Storm ...
Whistler anisotropy instabilities as the source of banded chorus: Van Allen Probes observations and particle-in-cell simulations
Magnetospheric banded chorus is enhanced whistler waves with frequencies (r)<(e), where (e) is the electron cyclotron frequency, and a characteristic spectral gap at (r)similar or equal to(e)/2. This paper uses spacecraft ...
Quiet time equatorial mass density distribution derived from AMPTE/CCE and GOES using the magnetoseismology technique
An inversion technique for estimating the properties of the magnetospheric plasma from the harmonic frequencies of the toroidal standing Alfven waves has been used to derive the global equatorial mass density covering ...
Kinetic Alfven waves in three-dimensional magnetic reconnection
Alfvenic waves are believed to be fundamentally important in magnetic reconnection. Kinetic dynamics of particles can break the Alfven speed limit in the evolution and propagation of perturbations during reconnection. In ...
