Discovery of 6 Uncatalogued High-Proper Motion Ultracool Dwarf Candidates from Gaia DR3

Puntos clave

This research aims to identify previously uncatalogued ultracool dwarf candidates in the solar neighborhood.
Performed data mining of the Gaia Data Release 3 catalog using strict astrometric and photometric ADQL queries.
Conducted rigorous visual vetting to confirm candidate status.
None of the identified sources are cataloged in SIMBAD or VizieR.
Identified 6 new ultracool dwarf candidates.
Candidates are classified as late M, L, and T dwarfs.
All candidates remain uncataloged in existing astronomical databases.

Resumen

The census of the solar neighborhood remains incomplete, particularly at the faint, ultracool end of the stellar main sequence and substellar regime (late M, L, and T dwarfs). In this research note, I report the identification of 6 new, highly probable ultracool dwarf candidates. The objects were discovered via data mining of the Gaia Data Release 3 (DR3) catalog using strict astrometric and photometric ADQL queries, followed by rigorous visual vetting. None of these sources are currently cataloged in SIMBAD or VizieR as confirmed astronomical objects.
