Research note identifies 6 new ultracool dwarf candidates, suggesting gaps in the solar neighborhood census.
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.
