VizieR Online Data Catalog: UCD Benchmarks with Detailed Abundances (Fisher+, 2024)
Abstract
Ultracool dwarfs (UCDs) are considered prime targets for galactic archeology due to their abundance, long lifespans, and the sensitivity of their spectra to chemical composition. To calibrate larger surveys, a sample of benchmark UCDs with robust abundances is necessary. We tabulate metallicities, alpha-enhancements and abundances of 13 elements, inferred from high-resolution spectra of 13 FGK primaries hosting a UCD companion.
