On the Scattering of Polarized Radio Emission by Langmuir Turbulence in a Plasma with a Magnetic Field
Bibliographic record
Abstract
This paper is concerned with effects of radio emission scattering in plasmas by Langmuir turbulent pulsations, as well as with the influence of these effects on polarization characteristics of radio emission frequencies above the electron plasma frequency and near the plasma frequency. It is shown that, the effects of radio emission scattering due to Langmuir turbulence can radically alter polarization characteristics of emission. The degree of polarization, when optical thicknesses with respect to the scattering process are of the order of unity, can change by as much as 30%, both at high frequencies and at frequencies, close to the plasma frequency. It is pointed out that the scattering by Langmuir turbulence gives rise to a dependence of the degree of circular polarization of radio emission on the wavelength even in a homogeneous magnetic field. Possible implications of the above effects for the solar atmosphere are briefly discussed.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
