Quark‐Nova Explosion inside a Collapsar: Application to Gamma Ray Bursts
Bibliographic record
Abstract
If a quark‐nova occurs inside a collapsar, the interaction between the quark‐nova ejecta (relativistic iron‐rich chunks) and the collapsar envelope leads to features indicative of those observed in Gamma Ray Bursts. The quark‐nova ejecta collides with the stellar envelope creating an outward moving cap (Γ∼ 1–10) above the polar funnel. Prompt gamma‐ray burst emission from internal shocks in relativistic jets (following accretion onto the quark star) becomes visible after the cap becomes optically thin. Model features include (i) precursor activity (optical, X‐ray, γ‐ray), (ii) prompt γ‐ray emission, and (iii) afterglow emission. We discuss SN‐less long duration GRBs, short hard GRBs (including association and nonassociation with star forming regions), dark GRBs, the energetic X‐ray flares detected in Swift GRBs, and the near‐simultaneous optical and γ‐ray prompt emission observed in GRBs in the context of our model.

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.
