Primeval very low-mass stars and brown dwarfs: II. the most metal-poor substellar object
SDSS J010448.46+153501.8 has previously been classified as an sdM9.5 subdwarf. However, its very blue J − K colour (-0.15 ± 0.17) suggests a much lower metallicity compared to normal sdM9.5 subdwarfs. Here, we re-classify this object as a usdL1.5 subdwarf based on a new optical and near-infrared spe...
