We reconstruct the star formation history (SFH) of the Orion star-forming complex using the highest-resolution age map currently available. It comprises 47 co-spatial and co-moving groups identified by the SigMA clustering algorithm, with homogeneously…","published":"2026-10-02T04:00:00Z","seen":"2026-10-02T20:03:24Z","lang":"en","source":{"id":"arxiv-astro-ph","name":"arXiv astro-ph (astrophysics)","domain":"arxiv.org","outlet":{"wikidata":"Q118398","name":"arXiv","type":"website","country":"US","designations":["bibliographic database","disciplinary repository","online database","open science tool","preprint server","website"]}},"via":"arxiv-astro-ph","topics":["space","astrophysics","astro-ph.ga","astro-ph.sr"],"authors":["Alena Rottensteiner, Jo\\~ao Alves, Stefan Meingast, Sebastian Hutschenreuter…"],"entities":[{"id":"Q8860","name":"Orion","type":"place"}],"story":"st_natd33ja2rzolhhly3sq","category":"science-technology","category_p":0.6600000262260437,"sentiment":"neutral","tone":0.03999999910593033,"political":0.029999999329447746}]}
