VizieR Online Data Catalog: Ultracool dwarfs in ALHAMBRA and COSMOS (Solano+, 2021)
Abstract
Using a VO methodology, we have built a catalogue of 897 candidate ultracool dwarfs (UCDs) found in the ALHAMBRA and COSMOS extragalactic surveys. In total, 16 of them were already known in SIMBAD. Our primary goal in this paper was not to carry out a detailed analysis on the properties of the found candidates but to define and assess a search methodology to be used for deeper and larger surveys like Euclid, whose excellent sensitivity makes it an ideal resource for the discovery of new UCDs, including BDs with very low effective temperatures.
