Optical properties of metal-poor T dwarf candidates
Context. Metal-poor brown dwarfs are poorly understood because they are extremely faint and rare. Only a few candidates have been identified as T-type subdwarfs in infrared surveys and their optical properties remain unconstrained. Aims: We aim to improve the knowledge of the optical properties of T subdwarf candidates to break the degeneracy
