cds-question@unistra.frspectroscopic-binary-starschemical-abundancesvisible-astronomyspectroscopyBinary interactions during the Asymptotic Giant Branch phase can lead to the formation of chemically peculiar stars such as Ba-, CH- and CEMP-s stars with overabundances of s-process elements as well as carbon. Only a few hundreds of these stars have been subject to detailed chemical and/or dynamical studies, typically in non-homogeneous samples. This work aims at compiling a systematic sample of s-process-polluted candidates using the fourth data release of the large spectroscopic survey GALAH. We also want to compare the chemical and orbital properties of these candidates with those of confirmed s-process-polluted stars to have stronger evidence of their nature. GALAH DR4 uses neural networks and automatic spectral analysis methods as well as data of a lower spectral resolution than normally used to characterise these objects. Because of this, before querying the survey, we built a validation sample of srich stars, for which we obtained UVES@VLT and HERMES@Mercator high-resolution (>80000) spectra and analysed them with traditional methods. We compare our stellar parameters and individual abundances with those of the survey and use this validation to define the thresholds that a star in GALAH DR4 must pass to be flagged as a good s-process-rich candidate. Based on our comparisons with the high resolution complementary spectra, we define thresholds on 5 quantities: [s/Fe]>0.40dex, [Y/Fe]>0.22dex, [Zr/Fe]>0.26dex, [Ba/Fe]>0.19dex, and La/Fe]>0.26dex. Results. We identified 1059 stars in GALAH DR4 that are good candidates to be s-process polluted stars, covering a broad parameter space (4000K<Teff<6000K, 0.5dex<logg<5.0dex, -2.0dex<[Fe/H]<0.5dex). They share many similarities with the samples of confirmed s-rich stars, especially their ratios of heavy over light s-elements ([hs/ls]), which strengthen our confidence in the purity of the sample. When crossmatching the sample with the literature, we find that only 7% of the candidates have measured orbital periods and eccentricities, limiting for now a full comparison with confirmed Ba and related star samples. However, their binary fraction is, as expected, higher than the one we found for the full GALAH DR4 catalogue. Our sample of candidates is almost five times larger than the number of currently confirmed polluted stars. This and the fact that it has been homogeneously treated by the GALAH survey open very interesting avenues to confront nucleosynthesis models as well as binary evolution models.2026A&A...712A.111Ehttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/712/A111CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/355 : Gaia DR3 Part 1.
