The NEMESIS Catalogue of Young Stellar Objects for the Orion Star Formation Complex

The NEMESIS Catalogue of Young Stellar Objects for the Orion Star Formation Complex (OSFC) consists of 27,879 sources located towards the OSFC, which have been previously identified as young stellar objects in the scientific literature. The catalogue includes panchromatic data products collated from existent literature and processed into thematic tables containing stellar parameters (T_eff, T_bol, spectral types, log(g), vsin(i), RV), infrared classes, equivalent widths of emission lines related to YSO accretion and star-disc interaction, and absorption lines such as lithium and lines related to source's gravity, as well as X-ray emission observables, photometric variability observables (variability periods and amplitudes), and multiplicity labels. When not derived by the authors but collated from the literature, entries are reported with an associated NASA/ADS bibcode pointing to the original scientific publication of that data product. The full description of the data collation and processing is available in the paper Roquette et al. (2025, A&A, in press)
