Abstract

fetched live from OpenAlex

The effect of ion temperature on nonlinear low frequency electrostatic potential structures is studied in a two component magnetized plasma with q-nonextensive hot electrons. The standard Sagdeev pseudo-potential approach is used to investigate the existence of ion acoustic solitons and double layers and their dependence on finite ion temperature. Only solitons are found to exist, with the amplitude decreasing as the ion temperature increases. For parameters typical of the auroral plasma, our model yields a soliton electric field amplitude of 22 mV/m, which is within the range measured by satellites, and as such can be helpful in understanding the electrostatic fluctuations phenomena in space environments.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
