An updated census of the young stellar population in Corona-Australis
Bibliographic record
Abstract
Corona-Australis is one of the nearest regions to the Sun with active star formation, but despite the close proximity (d~150 pc) our current picture of this starburst is not yet complete. Our team has recently revised the census of Corona-Australis stars using Gaia- DR2 data and discovered a distributed population of young stars located in the Galactic north of the dark clouds that is twice as numerous as the historically known stellar population concentrated around the densest cores of the region. Here, we build on the current census of stars in this region by combining the Gaia-EDR3 catalogue with astrometric and photometric ground-based data delivered by the Cosmic-DANCe project. We use our new sample of members and high-resolution spectroscopy to revisit the structure and kinematics of the Corona-Australis star-forming region.

How this classification was reachedexpand
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.
