V633 Cassiopeiae (LkHα 198) and V628 Cassiopeiae (MWC 1080) Revisited!
Bibliographic record
Abstract
We present the results of millimeter observations carried out at the James Clerk Maxwell Telescope (JCMT) during 1993 August and 1994 August of two Herbig Ae/Be stars, namely V633 Cas and V628 Cas. We follow up on the discovery reported by Hajjar & Bastien in 1994 of a probable protostellar object 20'' northwest of V633 Cas, which was also reported later that year by Sandell & Weintraub. It is the main source of emission in the region at millimeter wavelengths and probably the major contributor in the submillimeter up to 100 μm. We estimate a total mass of 0.12 M ☉ with a dust emissivity index of 0.35 ± 0.21. As seen in the 1990 maps by Nakano et al., V633 Cas C is at the center of a 13 CO cavity and at the position of observed molecular concentrations. Since it also falls at the center of a flattened structure seen in HCO + , it is most likely the source of the large-scale CO outflow studied by Levreault in 1988. From the dimension of the CO cavity, we estimate an age of 3 × 10 4 yr for the object. Based on a first estimate of its spectral energy distribution, we find a ratio of L bol / L 1.3 mm > 2 × 10 4 . Based on all these facts, we conclude that V633 Cas C is not a class 0 object but an extreme class I object. The dust emission from MWC 1080 is extended and flat with some features correlated with the optical ones. It is not evident that the grains we are sampling are related directly to the stellar environment.

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.
