Abstract:
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
(YSOs) that goes beyond survey-specific biases and can be employed for
training, validating, and refining the physical interpretation of
machine learning outcomes.
We aim to review the literature focussed 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 probing their youth.
Starting from the NASA/ADS database, the catalogue was assembled from
more than 200 peer-reviewed publications targeting the OSFC. We
collated data products relevant to the study of young stars into a
dedicated catalogue, which was complemented with data from large
photometric and spectroscopic surveys as well as the Strasbourg
Astronomical Data Center. We also added significant value to the
catalogue by homogeneously deriving YSO infrared classification
labels, through a comprehensive curation of labels concerning the
sources' multiplicity and through the derivation of probabilities of
the candidate YSOs in our catalogue being contaminant extragalactic
sources or giant stars.
Description:
The NEMESIS Catalogue of Young Stellar Objects for the Orion Star
Formation Complex (OSFC) consists of 27879 sources towards the OSFC,
previously identified as young stellar objects in the literature.
The catalogue includes a collection of panchromatic data products
collated from existent literature and processed into thematic tables
containing stellar parameters (Teff, Tbol, spectral types, log(g),
v*sin(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. Each
entry is reported with an associated NASA/ADS bibcode pointing to the
original scientific publication of that data product.
