Ultracool Dwarf Companion Catalogue UCDC
The Ultracool Dwarf Companion Catalogue consists of 278 multiple
systems, 32 of which are newly discovered, each with at least one
spectroscopically confirmed Ultracool Dwarf, within a 100 pc
volume-limited sample. This catalogue is compiled using the Gaia
Catalogue of Nearby Stars for stellar primaries and the Gaia Ultracool
Dwarf Sample for low-mass companions and includes 241 doubles, 33
triples, and 4 higher-order systems established from positional,
proper motion, and parallax constraints.
