High‐Latitude Neutral Mass Density Maxima [PDF]

Journal of Geophysical Research: Space Physics, 2017
AbstractRecent studies have reported that thermospheric effects due to solar wind driving can be observed poleward of auroral latitudes. In these papers, the measured neutral mass density perturbations appear as narrow, localized maxima in the cusp and polar cap.

Improving the estimation of thermospheric neutral density via two-step assimilation of in situ neutral density into a numerical model

Earth, Planets and Space, 2022
Neutral thermospheric density is an essential quantity required for precise orbit determination of satellites, collision avoidance of satellites, re-entry prediction of satellites or space debris, and satellite lifetime assessments.

Spatial distribution of low-energy plasma around 2 comet 67P/CG from Rosetta measurements [PDF]

, 2015
International audienceWe use measurements from the Rosetta plasma consortium (RPC) Langmuir probe (LAP) and mutual impedance probe (MIP) to study the spatial distribution of low-energy plasma in the near-nucleus coma of comet 67P/Churyumov-Gerasimenko ...

On the formation of density filaments in the turbulent interstellar medium [PDF]

, 2019
This study is motivated by recent observations on ubiquitous interstellar density filaments and guided by modern theories of compressible magnetohydrodynamic (MHD) turbulence. The interstellar turbulence shapes the observed density structures.

Approximating Isoneutral Ocean Transport via the Temporal Residual Mean

Fluids, 2019
Ocean volume and tracer transports are commonly computed on density surfaces because doing so approximates the semi-Lagrangian mean advective transport. The resulting density-averaged transport can be related approximately to Eulerian-averaged quantities

Comparison of a Neutral Density Model With the SET HASDM Density Database

Space Weather, 2021
The EXospheric TEMperatures on a PoLyhedrAl gRid (EXTEMPLAR) method predicts the neutral densities in the thermosphere. The performance of this model has been evaluated through a comparison with the Air Force High Accuracy Satellite Drag Model (HASDM ...

Density of Neutral Solitons in Weakly Disordered Peierls Chains [PDF]

, 1997
We study the effects of weak off-diagonal disorder on Peierls systems with a doubly degenerate ground state. We show that for these systems disorder in the electron hopping amplitudes induces a finite density of solitons in the minimal-energy lattice ...

Gas inlet impact on neutral density and recycle pattern with a disk shaped antenna in a miniature ion thruster through particle simulation

AIP Advances, 2021
The gas inlet configuration has a direct impact on the neutral density pattern within a miniature ion thruster. We aimed to investigate the impact the gas inlet configuration and neutral density pattern will have on the neutral recycle rate within a ...

Extraction of market expectations from risk-neutral density [PDF]

Zbornik radova Ekonomskog fakulteta u Rijeci : časopis za ekonomsku teoriju i praksu, 2015
The purpose of this paper is to investigate which of the proposed parametric models for extracting risk-neutral density; among Black-Scholes Merton, mixture of two log-normals and generalized beta; give the best fit.

The role of edge fueling in determining the pedestal density in high neutral opacity Alcator C-Mod experiments

Nuclear Materials and Energy, 2021
SOLPS-ITER modeling of EDA H-mode experiments on Alcator C-Mod find that the electron density pedestal structure is unaffected by increased gas fueling when approaching ITER-like opaqueness conditions.
