Description
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.
