Nevertheless, the large number of objects observed with an unprecedented precision, including trigonometric parallax, makes it an unrivaled dataset for studying the stellar-substellar boundary. In this paper, I review the contribution of the successive catalogues offered by the Gaia mission to study the low-mass, ultra-cool objetcs. I also present further characterisations and scientific exploitations of the Gaia sample.", "revisions": [ { "version": "v1", "updated": "2025-02-07T14:15:37.000Z" } ], "analyses": { "keywords": [ "ultracool dwarfs", "reddest part", "main sequence", "gaia sample", "gaia optical observations" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
