Eclipsing spectroscopic binaries from Gaia DR3 orbits and TESS: survey data products (93 systems at periods of 13–119 days)

Abstract

Data products of the survey of eclipses at the conjunctions predicted by Gaia DR3 single-lined spectroscopic orbits in TESS light curves, accompanying the paper "Eclipsing spectroscopic binaries from Gaia DR3 orbits and TESS: 93 systems at periods of 13–119 days". 9 389 orbits searched in up to three TESS sectors each; 227 stars with two consistent primary dips and 561 with one; 425 candidates absent from the variability catalogues vetted on every available sector; 93 eclipsing systems established at periods of 13–119 days (21 beyond 30 d), 90 of them never identified as eclipsing before, 54 with companion masses and radii from detached-binary fits. The record includes an integrity and reproduction check (check_z4.py) that recomputes the paper's funnel from the deposited files without a network connection. Contents: the selection of Gaia DR3 SB1 orbits observed by TESS with a conjunction predictable to one day (selection_v2.parquet); every predicted conjunction tested, with the depth and significance of the deepest dip and the control level (conjunctions.jsonl); the candidate stars with their star-level evidence and automatic catalogue checks (candidate_stars.jsonl); the batch vetting of the candidates absent from the variability catalogues — difference imaging, dips at predicted conjunctions in every sector, eclipse ephemerides, Gaia primary parameters, companion masses, verdicts (vetting_summary.csv, vet_*.json); and the eclipse fits of the confirmed systems (fits_table.csv, fit_*.json). Light curves are not included: they are the SPOC, TESS-SPOC and QLP products on MAST. Access is embargoed until the acceptance of the paper; the DOI can be cited meanwhile. CC BY 4.0. Version 1.1.0 supersedes 1.0.0 (doi:10.5281/zenodo.22998329): the funnel counts only the 9 389 selected stars (788 flagged, 561 single-dip); the candidate file has one line per source with grades recomputed from the conjunction rows; Table 3 uses the DR3 eccentricity for four partial eclipses whose free fit departs from it by more than 3σ; the software is lctriage 1.2.0 (doi:10.5281/zenodo.21916566, all versions). The data rows are unchanged. Version 1.1.1 changes only the software reference inside README.md and CITATION.cff: version 1.1.0 (doi:10.5281/zenodo.23003140) cited lctriage 1.2.0 by a version DOI that was never registered. Version 1.2.0 supersedes 1.1.1 (doi:10.5281/zenodo.23003581). The mass–radius sample of the paper now requires a reduced chi-square of the detached-binary fit of at most 10: six fits above it, previously counted as partial eclipses, are counted as poorly fitted, and the sample has 54 systems (34 full and 20 partial eclipses) instead of 60; check_z4.py applies the rule. Table 3 is regenerated accordingly: three partial eclipses are computed with the DR3 eccentricity, with a/R1 printed rescaled together with R2; K1 is given in km s−1. Figures 4 and A.1 are redrawn. The data rows are unchanged.
