摘要：
过去十年中，机器学习方法在年轻恒星演化研究中的应用日益增多。这一趋势导致对超越巡天特定偏差、可用于训练、验证和完善机器学习结果物理解释的全面年轻恒星天体（YSO）数据库的需求不断增长。我们回顾了聚焦于猎户座恒星形成复合体（OSFC）的文献，以编制该区域先前已识别YSO候选体的详尽星表，包括整理与其年轻特性相关的可观测数据。从NASA/ADS数据库出发，我们从200多篇同行评审出版物中汇集了YSO候选体。我们将与YSO研究相关的数据产品整理到一个专用星表中，并辅以来自大型测光和光谱巡天以及斯特拉斯堡天文数据中心的数据。我们还通过同质化地推导YSO红外分类标签，并对涉及源多重性的标签进行全面整理，为星表增添了重要价值。最后，我们采用全色方法推导了星表中源为污染河外星系源或巨星的概率。我们呈现了针对OSFC的NEMESIS YSO星表，其中包含为27879个源整理的数据，覆盖了从原恒星到无盘年轻恒星的前主序演化的整个质量范围和各个阶段。该星表包括处理成光谱能量分布的全色测光数据集合、恒星参数、红外类别、与YSO吸积和恒星-盘相互作用相关的发射线等效宽度，以及锂等吸收线和与源引力相关的谱线、X射线发射可观测数据、测光变率可观测数据和多重性标签。
英文摘要：
The past decade has seen a rise in the use of Machine Learning methods in the study of young stellar evolution. This trend has led to a growing need for a comprehensive database of young stellar objects (YSO) that goes beyond survey-specific biases and that can be employed for training, validation, and refining the physical interpretation of machine learning outcomes. We reviewed the literature focused on the Orion Star Formation complex (OSFC) to compile a thorough catalogue of previously identified YSO candidates in the region including the curation of observables relevant to probe their youth. Starting from the NASA/ADS database, we assembled YSO candidates from more than 200 peer-reviewed publications. We collated data products relevant to the study of YSOs into a dedicated catalogue, which was complemented with data from large photometric and spectroscopic surveys and in the Strasbourg astronomical Data Center. We also added significant value to the catalogue by homogeneously deriving YSO infrared classification labels and through a comprehensive curation of labels concerning sources' multiplicity. Finally, we used a panchromatic approach to derive the probabilities that the sources in our catalogue were contaminant extragalactic sources or giant stars. We present the NEMESIS catalogue of YSOs for the OSFC, which includes data collated for 27879 sources covering the whole mass spectrum and the various stages of pre-Main Sequence evolution from protostars to diskless young stars. The catalogue includes a collection of panchromatic photometric data processed into spectral energy distributions, stellar parameters, infrared classes, equivalent widths of emission lines related to YSOs accretion and star-disk interaction, and absorption lines such as lithium and lines related to source's gravity, X-ray emission observables, photometric variability observables, and multiplicity labels.
