Abstract
\n We report on the physical properties of the disk-like structure \nof B8 IIIp star 36 Lyncis from line syntheses of phase-resolved, \nhigh resolution spectra obtained from the \nInternational Ultraviolet Explorer archives and from\nnewly obtained ground-based spectra of the Hα absorption profile. \nThis disk is highly inclined to the rotational axis and betrays its existence\nevery half rotation cycle as one of two opposing sectors pass in front of the \nstar. Although the disk absorption spectrum is at least ten times too weak to \nbe visible in optical iron lines during these occultations, its properties can \nbe readily examined in a large number of UV “iron curtain” lines because of\ntheir higher opacities. The UV Fe II and Fe III lines in particular permit a\ndetermination of the disk temperature: $7500\\pm500$ K and a column density \nof $3_{-1.5}^{+3}\\times10^{20}$ cm-2.\nThe analysis of the variations of the UV resonance lines brings out\nsome interesting details about the radiative properties of the disks: \n(1) they are optically thick in the C IV and Si IV doublets, \n(2) the range of excitation of the UV resonance lines is larger at the \nprimary occultation ($\\phi = 0.00$) than at the secondary one,\nand (3) the relative strengths of the absorption peaks \nfor the two occultations \nvaries substantially from line to line. We have modeled the absorptions of \nthe UV C IV resonance and Hα absorptions \nby means of a simulated disk \nwith opaque and translucent components. Our simulations suggest that\na gap separates the star and the inner edge of the disk. The disk \nextends radially out to ≥10 $R_{*}$. The disk scale height \nperpendicular to the plane is ≈1 $R_{*}$. \nHowever, the sector causing the primary occultation is about \nfour times thicker than the opposite sector. The C IV scattering region \nextends to a larger height than the Hα region does, probably because\nit results from shock heating far from the cooler disk plane.\n\n\n

Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
