Abstract

fetched live from OpenAlex

Detailed photoionization and radiative acceleration of self-similar magnetocentrifugal accretion disk winds are explored. First, a general-purpose hybrid magnetocentrifugal and radiatively driven wind model is defined. Solutions are then examined to determine how radiative acceleration modifies magnetocentrifugal winds and how those winds can influence radiative driving in active galactic nuclei. For the models studied here, both radiative acceleration by bound-free ("continuum driving") and bound-bound ("line driving") processes are found to be important, although magnetic driving dominates the mass outflow rate for the Eddington ratios studied ( L / L Edd = 0.001-0.1). The solutions show that shielding by a magnetocentrifugal wind can increase the efficiency of a radiatively driven wind, and also that within a magnetocentrifugal wind, radiative acceleration is sensitive to both the column in the shield, the column of the wind, and the initial density at the base of the wind.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
