Bolometric luminosities and radii in solar units for a subset of ultracool dwarfs (gaiadr3.gold_sample_ucd)
The table has 21062 rows, 7 columns.
Description
The table contains the bolometric luminosities and radii in solar units for a subset of ultracool dwarfs from the Gaia DR3 catalogue, as well as some intermediate quantities used in the selection of sources and in the derivation of the luminosities and radii. For more details please refer to DR3-DPACP-123.
