Primeval very low-mass stars and brown dwarfs - IV. New L subdwarfs, Gaia astrometry, population properties, and a blue brown dwarf binary

Z. H. Zhang, M. C. Galvez-Ortiz, D. J. Pinfield +13

We present 27 new L subdwarfs and classify five of them as esdL and 22 as sdL. Our L subdwarf candidates were selected with the UKIRT Infrared Deep Sky Survey and Sloan Digital Sky…

Primeval very low-mass stars and brown dwarfs - III. The halo transitional brown dwarfs

Z. H. Zhang, D. J. Pinfield, M. C. Galvez-Ortiz +11

We report the discovery of an esdL3 subdwarf, ULAS J020858.62+020657.0, and a usdL4.5 subdwarf, ULAS J230711.01+014447.1. They were identified as L subdwarfs by optical spectra obt…
