With the release of Gaia DR2, the distance measurements to the Orion complex are now good enough that the 3D structure of the complex can be explored. Here we test the hypothesis that, due to non- trivial structure and dynamics, and age spread in the Orion complex, the chemical enrichment of youngest stars by early core-collapse supernovae can be observed. We obtained spectra of 794 stars of the Orion complex with the HERMES spectrograph at the Anglo Australian telescope as a part of the GALAH and GALAH-related surveys. We use the spectra of ~300 stars to derive precise atmospheric parameters and chemical abundances of 25 elements for 15 stellar clusters in the Orion complex. We demonstrate that the Orion complex is chemically homogeneous and that there was no self-pollution of young clusters by core-collapse supernovae from older clusters; with a precision of 0.02 dex in relative alpha-elements abundance and 0.06 dex in oxygen abundance we would have been able to detect pollution from a single supernova, given a fortunate location of the SN and favourable conditions for ISM mixing. We estimate that the supernova rate in the Orion complex was very low, possibly producing no supernova by the time the youngest stars of the observed population formed (from around 21 to 8 Myr ago).2021MNRAS.506.4232Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/506/4232CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/MNRAS/478/4513 : GALAH Survey DR2 (Buder+, 2018)J/MNRAS/506/150 : The GALAH+ Survey DR3 (Buder+, 2021)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/506/4232https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/506/4232http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/506/4232https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/506/4232https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/506/4232http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/506/4232GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/506/4232/table (*Photometric, spectroscopic parameters and abundances for each stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/506/4232/table?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/506/4232/table?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/506/4232/table?GETtext/xml+votable180.050000true85.14679.90420.0055555555555555565/5715 5720 5723 5726 5934 6/22815 22829 22834 22837-22842 22844-22845 22858-22859 22884-22886 22888-22889 22898 22981 22992-22993 22995 22998 23695 23704 23706 23717 23719 23728 23730-23731https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/506/4232?format=asciiOpticalInfrareddefaultJ/MNRAS/506/4232/table*Photometric, spectroscopic parameters and abundances for each starsGaiaDR2Unique source identifier (id)meta.id;meta.mainrecnoRecord number assigned by the VizieR team.
