Abstract

I present WISEA J052305.94-015356.1 as a new candidate extremely metal-poor T subdwarf (esdT), based on its distinctive infrared colours and high proper motion ( $\sim500\$ mas/yr). Spectroscopic follow-up is now needed to confirm it is a member of this newly discovered class of substellar objects.
